CRUISE LINES ARE FINALLY DONE TOLERATING THESE 5 ONBOARD BEHAVIORS
Sep
Imagine you’re standing near Guest Services on a cruise ship when an angry passenger begins shouting at an employee.
The passenger is furious about a problem with his vacation. Complaining isn’t the issue. Passengers have every reason to raise legitimate concerns when something goes wrong.
But then the confrontation changes.
His comments become insulting. He starts targeting the employee personally. The employee tells him to stop.
Another passenger watching nearby asks the question many cruisers probably have:
Can someone actually get in serious trouble—or even be removed from a cruise ship—for behavior like this?
The answer is yes: depending on the cruise line, the conduct and the circumstances, violations of guest-conduct and safety policies can lead to serious consequences.
And abusive behavior is only one example.
Current policies from major cruise operators including Royal Caribbean Group, Norwegian Cruise Line and MSC Cruises explicitly address abusive language, violence or harassment, unsafe behavior, railing violations and failure to follow safety or security instructions.
There is an important clarification before we get to the five behaviors, though.
The headline “Cruise Lines Are Finally Done Tolerating These 5 Onboard Behaviors” should not be interpreted to mean the entire cruise industry just announced five brand-new rules at the same time.
Many of these standards have existed in cruise guest-conduct policies already.
What matters to passengers is that these aren’t merely suggestions about cruise etiquette. Some are explicit conduct and safety rules—and violating them can have consequences.
Here are five behaviors you should take seriously.
1. Verbally Abusing, Threatening or Harassing Crew and Other Passengers
There’s a major difference between complaining and abusing someone.
You paid thousands of dollars for a cruise and your cabin has a problem?
Complain.
Your shore excursion was canceled and you need help understanding your options?
Ask Guest Services.
You think you’ve been incorrectly charged?
Raise the issue.
But paying for a cruise doesn’t erase the ship’s guest-conduct rules.
Royal Caribbean Group’s current Guest Health, Safety and Conduct Policy explicitly states that verbally abusive or offensive language directed at guests, crew members, government officials or others is not permitted. Statements or conduct threatening prohibited or illegal activity are also forbidden.
Norwegian Cruise Line likewise states that verbally abusive or offensive language directed toward others, including crew members and guests, isn’t permitted.
MSC’s policy goes one step further in its wording by explicitly referring to verbally abusive, offensive or discriminatory language directed at others.
Discrimination isn’t “just complaining”
Consider the opening scenario.
An angry passenger says something discriminatory to a Black crew member, then argues:
“I paid for this cruise!”
The money he paid isn’t the relevant issue.
A guest can raise a complaint without directing discriminatory or abusive language toward the employee handling it.
That’s an important distinction because social-media clips often remove context and make these confrontations look like:
Passenger complains → cruise line punishes passenger.
The actual issue may be what the passenger does during that confrontation.
There’s a difference between:
“I’m unhappy with how this was handled and I want to speak with a manager.”
and personally abusing, threatening or harassing the employee.
What should you do when you’re genuinely angry?
Stay focused on the problem.
Explain what happened. Ask what options are available. Request a supervisor if necessary. Keep receipts, screenshots or other documentation if they’re relevant.
You can be firm without becoming abusive.
And if you feel yourself becoming too angry to have a productive conversation, walking away and returning later may produce a much better outcome than turning a service complaint into a conduct problem.
2. Fighting, Violence, Harassment and Unwanted Physical Contact
This one should surprise absolutely nobody.
But it’s worth emphasizing because cruise vacations combine large numbers of people, nightlife, crowded public areas and alcohol—and an argument that starts small can escalate quickly.
Major cruise-line policies explicitly prohibit conduct well beyond simply “starting a fight.”
Royal Caribbean Group lists inappropriate or abusive behavior including uninvited physical contact, harassment and violence, along with vandalism, theft and other prohibited conduct.
Norwegian’s current guest-conduct information similarly lists uninvited physical contact, harassment and violence among behavior that isn’t permitted.
MSC uses substantially similar categories in its current policy.
You don’t necessarily need to throw a punch to cross the line
That’s an important takeaway.
Some passengers may imagine the rule is simply:
“Don’t fight.”
The actual policy language is broader.
Harassment and unwanted physical contact can matter too.
That means a confrontation doesn’t have to become a full-scale fistfight before it becomes a serious conduct issue.
If another passenger is irritating you, don’t escalate it physically.
If someone takes “your” seat, don’t grab them.
If someone bumps into you at the buffet, don’t shove them.
If a dispute begins in a bar, don’t turn it into a physical confrontation.
Find a crew member or security if the situation requires intervention.
Cruise ships aren’t law-free environments
A vacation at sea can sometimes create the illusion that normal standards have temporarily disappeared.
They haven’t.
Ships have security procedures, shipboard rules and obligations connected to the jurisdictions in which they operate.
Royal Caribbean’s current policy specifically identifies possible security, management or law-enforcement intervention among its potential enforcement responses.
So “what happens at sea stays at sea” is a terrible philosophy when it comes to passenger behavior.
3. Climbing, Sitting or Standing on Railings and Other Dangerous Behavior
Here’s one of the most important cruise safety rules on this list.
Don’t climb on railings.
Don’t sit on railings.
Don’t stand on railings.
Don’t lean over protective barriers in ways the ship prohibits simply because you want a better photograph.
Royal Caribbean Group’s policy specifically prohibits sitting, standing, jumping, lying or climbing on, over or across interior or exterior railings and other protective barriers. It also prohibits tampering with ship equipment, facilities or systems.
Norwegian similarly prohibits sitting, standing, lying or climbing on, over or across railings or protective barriers and identifies failure to follow security instructions as unsafe behavior.
MSC’s policy likewise addresses unsafe railing behavior and tampering with safety-related ship equipment or facilities.
The Instagram photo isn’t worth it
Cruise ships can provide extraordinary photo opportunities.
Sunset.
Open ocean.
A dramatic wake behind the ship.
A beautiful port appearing on the horizon.
But the existence of a railing is not an invitation to climb onto it for a better angle.
A protective barrier should be treated as exactly that: a protective barrier.
This is also why passengers shouldn’t encourage someone else to perform dangerous stunts just to record a viral video.
If getting the shot requires violating a safety barrier, find another shot.
“I was only there for five seconds” doesn’t change the risk
Unsafe behavior doesn’t become safe because it’s brief.
And when crew members intervene, arguing that you’re an experienced traveler or strong swimmer misses the point.
The ship’s safety rules still apply.
Royal Caribbean’s current policy describes failure to follow health, safety or security instructions or policies as strictly prohibited.
Which leads directly to Behavior #5—but first, there’s another rule that causes frequent confusion.
4. Smoking or Vaping Where It Isn’t Permitted
Smoking policies can differ by cruise line and ship, particularly when it comes to designated smoking areas and casinos.
But one principle is easy to understand:
If smoking or vaping is restricted to designated locations, don’t assume your cabin or balcony is one of them.
Royal Caribbean Group’s current policy says smoking isn’t permitted inside staterooms or on stateroom balconies. It also prohibits smoking in dining venues, theaters, bars, lounges, hallways, elevators, jogging tracks and most indoor areas, while designated smoking areas are provided. The policy says electronic cigarettes are permitted only within designated smoking areas.
Royal Caribbean also says a cleaning fee will be applied to the onboard account when a guest violates its no-smoking policy inside a stateroom or on a stateroom balcony.
That’s much stronger evidence than simply calling balcony smoking “bad etiquette.”
It’s a policy issue.
“But I’m outside” isn’t enough
A cabin balcony may feel like private outdoor space.
That doesn’t automatically make smoking there permissible.
Passengers should check their cruise line’s current smoking policy rather than relying on intuition.
The same applies to vaping.
Some travelers assume that because an electronic cigarette doesn’t produce traditional cigarette smoke, it can automatically be used anywhere.
Don’t make that assumption.
Royal Caribbean’s current policy specifically addresses electronic cigarettes and restricts their use to designated smoking areas.
Don’t copy another passenger
This is another classic cruise mistake.
You see someone smoking somewhere and conclude:
“Well, they’re doing it, so this must be a smoking area.”
Not necessarily.
Look for the ship’s designated-smoking signage or ask Guest Services or a crew member.
Another passenger breaking a rule doesn’t turn the location into an approved smoking area.
And don’t assume the policy from your previous cruise applies identically to your next one.
Check the line and ship you’re actually sailing.
5. Refusing to Follow Crew Safety and Security Instructions
This may be the most underestimated behavior on the entire list.
A passenger hears a crew member say:
“Sir, you need to step back.”
And responds:
“You can’t tell me what to do. I paid for this vacation.”
That’s the wrong way to think about shipboard safety.
Crew instructions aren’t automatically optional because you’re a paying guest.
Royal Caribbean Group’s policy states that failure to follow health, safety or security instructions or policies is prohibited. Its security section also requires guests to follow instructions provided by onboard security personnel.
Norwegian identifies failure to follow security instructions as unsafe behavior.
MSC does the same in its current Guest Conduct Policy.
This can apply before the ship even sails
One particularly important detail in Royal Caribbean Group’s policy is its scope.
Its stated conduct standards extend beyond simply standing on the ship’s open deck. The policy describes standards covering parts of the cruise vacation including transfers, terminals, the vessel, ports of call, shore excursions and private destinations.
So passengers shouldn’t think:
“The rules don’t start until we’re at sea.”
Depending on the relevant policy and circumstances, conduct requirements can extend much further across the cruise experience.
Muster and emergency instructions are not entertainment
Safety procedures may feel routine, especially to experienced cruisers.
But familiarity doesn’t make them irrelevant.
Royal Caribbean’s policy specifically requires guests to complete the mandatory safety-drill requirements and follow health and safety instructions associated with the drill.
When a crew member is giving a legitimate safety or security instruction, the smartest response isn’t to debate whether you personally think it’s necessary.
Follow the instruction.
Questions can be addressed afterward when appropriate.
Can a Passenger Really Be Removed From a Cruise Ship?
Yes, removal can be among the possible consequences—but this needs careful wording.
You should not read this article as saying:
“Raise your voice once and you’re automatically thrown off the ship.”
That’s not what the policies establish.
Royal Caribbean Group’s current policy lists a range of potential enforcement actions depending on its assessment of a violation or safety/security concern. Those can include intervention by security, management or law enforcement; loss of certain onboard privileges; confiscation of prohibited items where applicable; effects on loyalty benefits or tier status; denial of boarding; removal from the vessel; and denial of future boarding.
The policy also says guests removed or denied boarding because of a policy violation are responsible for their own accommodation and transportation home.
That’s potentially a very expensive ending to a vacation.
But again:
These are possible enforcement actions, not an automatic penalty chart.
The facts and severity matter.
The cruise line matters.
The behavior matters.
The circumstances matter.
So avoid viral claims like:
“Do this once and you’ll definitely be kicked off.”
A more accurate statement is:
Serious or repeated violations can potentially result in significant enforcement action, including removal in some circumstances.
Are These 5 Cruise Rules New?
Mostly, that’s the wrong question.
The evidence reviewed here doesn’t establish that Royal Caribbean, Norwegian and MSC all suddenly introduced these exact five rules at the same time.
In fact, the relevant guest-conduct frameworks have existed in various forms before.
That’s why the word “FINALLY” in our headline is best understood as an editorial hook about cruise lines enforcing behavioral standards—not as a claim that September 2026 brought one new industry-wide rulebook.
There is no single universal “Five Bad Behaviors Act” governing every cruise company.
Each line has its own terms, policies and enforcement mechanisms.
What is striking, however, is how much overlap exists in the current policies we reviewed.
Abusive language?
Addressed.
Violence and harassment?
Addressed.
Dangerous railing behavior?
Addressed.
Ignoring safety/security instructions?
Addressed.
That should tell passengers something important:
These aren’t simply complaints from people who want everyone onboard to behave more politely.
Several are explicitly covered by written cruise-line policies.
What If Another Passenger Is Breaking the Rules?
Don’t turn yourself into ship security.
If another guest appears to be behaving dangerously, violently or illegally, alert appropriate crew or security personnel rather than escalating the confrontation yourself.
Royal Caribbean’s current policy specifically asks guests to report unsafe or possibly illegal behavior to security staff or ship management.
Norwegian similarly tells guests who become aware of unsafe or possibly illegal behavior to report it to ship security or other ship management.
This matters especially when alcohol or aggression is involved.
You don’t know how another passenger will respond.
You also may not know the full context.
Get the professionals involved.
What These Rules Mean for Normal Passengers
Most cruisers don’t need to be worried.
You don’t have to spend your vacation walking around terrified that one wrong sentence will get you removed from the ship.
The practical lesson is much simpler.
Treat crew members and fellow passengers respectfully.
Don’t threaten or harass people.
Keep your hands to yourself.
Don’t climb safety barriers.
Smoke or vape only where the cruise line allows it.
And when crew or security gives you a legitimate safety instruction, follow it.
That’s not a difficult standard.
In fact, most passengers already behave this way without thinking about it.
The rules become important when someone decides that because they paid for a vacation, normal boundaries no longer apply.
They do.
5 Things Not to Do on a Cruise — Quick Checklist
Before your next sailing, remember these five categories:
1. Don’t verbally abuse, threaten or harass crew members or other passengers.
2. Don’t fight, use violence or initiate unwanted physical contact.
3. Don’t climb, sit or stand on railings or engage in other prohibited unsafe behavior.
4. Don’t smoke or vape in places where your cruise line prohibits it.
5. Don’t refuse legitimate crew safety or security instructions.
These aren’t five universal new laws announced simultaneously by every cruise line. They are a fact-safe summary of important conduct categories supported by current policies from major operators reviewed for this article.
FAQ: Cruise Ship Behavior Rules
Can a cruise line remove a passenger for bad behavior?
Potentially, yes. For example, Royal Caribbean Group identifies removal from the vessel among possible enforcement actions for policy violations or safety/security concerns. It is not an automatic consequence for every incident.
Can you get in trouble for yelling at cruise staff?
Simply making a complaint isn’t the same as violating a conduct policy. However, Royal Caribbean, Norwegian and MSC policies prohibit abusive or offensive language toward others, with MSC explicitly including discriminatory language.
Are fights prohibited on cruise ships?
Yes. Current guest-conduct policies reviewed from Royal Caribbean, Norwegian and MSC prohibit violence and also address harassment and uninvited physical contact.
Can you sit on a cruise ship railing?
Do not assume so. The policies reviewed from these major operators explicitly prohibit sitting or climbing on or across protective railings/barriers, with wording varying somewhat by line.
Can you smoke on a cruise ship balcony?
It depends on the cruise line, so always check your specific operator. Royal Caribbean’s current policy prohibits smoking in staterooms and on stateroom balconies and provides designated smoking areas elsewhere.
Are vapes allowed everywhere because they aren’t cigarettes?
No. Do not assume vaping is exempt from smoking restrictions. Royal Caribbean, for example, says e-cigarettes are permitted only in designated smoking areas.
Do passengers have to follow crew instructions?
Cruise policies can require passengers to follow health, safety or security instructions. Royal Caribbean, Norwegian and MSC all have current policy language addressing failure to follow relevant safety/security instructions.
Final Takeaway: Your Cruise Fare Doesn’t Buy an Exemption From the Rules
Return to that confrontation at Guest Services.
The angry passenger’s argument is:
“I paid for this cruise!”
That’s true.
But thousands of other passengers also paid for their cruise.
Crew members are there to work without being subjected to prohibited abusive conduct.
Other guests deserve a vacation without violence or harassment.
Safety barriers exist for a reason.
Designated smoking rules exist for a reason.
And crew safety instructions don’t become optional because a passenger disagrees with them.
The strongest takeaway from the current guest-conduct policies isn’t that cruise lines have suddenly created five shocking new bans.
It’s something more useful:
Your cruise is a vacation, but it still has rules.
Royal Caribbean, Norwegian and MSC all publish guest-conduct standards addressing multiple forms of abusive or unsafe behavior. Depending on the cruise line and circumstances, violating those standards can trigger enforcement action—and in serious cases, those possible consequences can extend as far as removal or future boarding restrictions.
So enjoy the ship.
Enjoy the food.
Enjoy the bars, shows, pools and ports.
Complain when you have a legitimate problem.
But don’t confuse being a paying passenger with having permission to abuse people, start fights, ignore safety barriers, smoke wherever you want or disregard legitimate safety instructions.
Before sailing, check the current guest-conduct and safety policy for your specific cruise line, because rules and enforcement details can change.
The easiest way to avoid becoming the passenger everyone remembers for the wrong reason?
Respect the crew, respect your fellow passengers—and respect the ship’s rules.
