If you’re cruising with teenagers, booking them their own cabin can make life considerably easier. You get a little more space, they get some independence, and nobody has to spend a week climbing over sofa beds and Pullman beds every time they want to get to the bathroom.
But how old do children actually need to be before they’re allowed their own cruise cabin?
It sounds like a simple question, but unfortunately the answer depends entirely on which cruise line you’re sailing with. And getting it wrong could cause much bigger problems than an argument over who gets the balcony.
A Mum Was Almost Denied Boarding Over Her Teenagers’ Cabin
This caught my attention after I saw a recent Instagram video from a single mum who had travelled from the UK to Florida with her three teenage children for a Princess cruise.
Her two eldest teenagers were booked into one cabin, with the oldest being 17, while she was staying separately with her other child.
She hadn’t just assumed this would be OK either. She said she had checked the arrangement several times during the booking process and had received confirmation from Princess that her teenagers could share their own cabin.
But when the family arrived at the cruise terminal in Florida, they were initially told they couldn’t board because the two teenagers needed an adult staying in their room.
Even after explaining that she had already checked the rules, a supervisor apparently agreed with the check-in agent that the booking wasn’t allowed.
Imagine flying all the way from the UK to Florida with three children and then being told at the terminal that you might not be getting on the ship.
Around ten minutes later, the decision was reversed and the family was allowed to board with the cabins exactly as they had booked them. So thankfully it ended well, but it was hardly the relaxing start to a cruise they’d been hoping for.
And according to Princess Cruises’ own published rules, the original booking should indeed have been permitted.
Princess Cruises – 16 Years Old
Princess normally says that guests under 21 must share a stateroom with somebody aged 21 or older, which is presumably where some of the confusion at check-in came from.
However, there’s an important exception for families booking more than one cabin.
Princess says that for family groups with multiple staterooms, there only needs to be at least one person aged 16 or older in each stateroom, provided the children are travelling with a parent or legal guardian.
So a 17-year-old sharing with a younger teenage sibling while their mum stays in another cabin absolutely appears to meet Princess Cruises’ published requirements.
It’s a really useful reminder that you shouldn’t just look at the headline minimum age for booking a cruise. Family bookings often have completely different rules.
And if you do have an unusual cabin arrangement, I’d be tempted to save a screenshot or printed copy of the cruise line’s policy before you travel. Hopefully you’ll never need it, but after seeing what happened to this family, I’d rather have it with me.

Royal Caribbean – Any Age, If They’re Next Door Or Opposite
Royal Caribbean is much more flexible about children having their own cabin, although where that cabin is located matters.
Its UK booking conditions state that a cabin occupied solely by minors must be adjacent to the parent or legal guardian’s cabin, which Royal Caribbean defines as either directly next door or directly opposite.
So you could potentially have quite young children sleeping in another cabin, provided you’re staying right beside them.
Obviously whether you’d actually want a six-year-old sleeping alone across the corridor is another question entirely, but the cruise line’s policy doesn’t set a specific minimum age for the child in this situation.
This can be particularly handy with older children and teenagers because you don’t necessarily need connecting cabins. If there’s an inside cabin directly opposite your balcony cabin, for example, you may be able to put the teenagers in there.
Royal Caribbean does have different rules surrounding the minimum age to travel independently, particularly depending on where the cruise departs from, but that’s separate from children having their own cabin while travelling with their parents.
Celebrity Cruises – Any Age, If They’re Next Door Or Opposite
Celebrity Cruises has essentially the same rule as Royal Caribbean, which isn’t too surprising considering both cruise lines are owned by Royal Caribbean Group.
Celebrity says that individual staterooms occupied solely by minors must be adjacent to the parent or legal guardian’s cabin, again meaning directly next door or directly opposite.
There isn’t a specific minimum age listed for the children occupying that cabin.
So if you’re booking two rooms for a family, location is much more important than the age of the teenagers. Don’t book Mum and Dad on Deck 8 and the kids three decks below and assume it will be fine.
Carnival Cruise Line – It Depends On The Child’s Age
Carnival probably wins the award for having the most detailed set of rules.
For bookings made from 1st February 2025 onwards, guests aged 20 or younger generally need to travel with a relative or guardian who is at least 25, although there are exceptions including parents aged 21 to 24 travelling with their own children.
I actually posted about this on Facebook recently after discovering that an unmarried couple aged 20 and 24 couldn’t share a cabin on a Carnival cruise without somebody aged 25 or older on the booking.
They could be engaged, have three children together, own a house and run a business, but apparently they’re not responsible enough to share a cruise cabin!
There are exceptions for married couples and qualifying military personnel, but it’s still a pretty unusual rule.
Back to families though, and where the children’s cabin can be located then depends on their ages.
Children aged 14 and under need to be booked either in the same cabin as their relative or guardian, or in a connecting cabin.
Those aged 15 to 17 get more freedom. Their cabin can be up to three staterooms away from the relative or guardian aged 25 or over, although the bookings need to be properly linked.
Guests aged 18 to 20 used to have more flexibility, with no restrictions on where their cabin could be located. But Carnival changed its rules for new bookings made from 1st October 2026.
Now, anyone aged 15 to 20 must be booked into a cabin no more than three staterooms away from their accompanying adult aged 25 or over.
Carnival has also tightened the rules for larger groups, requiring at least one responsible adult for every five minors.
This is one where I definitely wouldn’t just book two cabins online and hope for the best. Carnival is quite specific about how bookings involving minors need to be set up, so make sure the reservations are linked correctly.
Norwegian Cruise Line – Connecting Or Adjoining
Norwegian Cruise Line generally requires anyone under 21 to be accompanied by somebody aged 21 or older in the same cabin, or in a connecting/adjoining stateroom.
Its full terms add that two people under 18 can share a cabin without an adult inside it, provided somebody aged 21 or over is staying in the adjoining stateroom.
That makes Norwegian less flexible than Royal Caribbean if you were hoping to put the children a few doors away or across the corridor.
You’ll want to pay particular attention to the actual cabin layout when booking too. Cruise lines don’t always use words such as “adjacent”, “adjoining” and “connecting” in exactly the same way, and a connecting cabin specifically means there’s a door between the two rooms.
MSC Cruises – From 8 Years Old In Some Cases
MSC Cruises has perhaps the most complicated policy of all, but it does allow surprisingly young children to stay without an adult in their cabin in certain circumstances.
The exception applies when minors are travelling with only one parent or legal guardian, who must be travelling with between two and five children. The parent must specifically request separate accommodation and sign a waiver.
MSC will allow either one child aged at least 12 to occupy the cabin, or two children to share provided the oldest is at least 12 and the youngest is at least 8. More than two minors cannot stay alone together in the cabin.
There are then different rules depending on the ship.
On MSC Lirica, MSC Armonia, MSC Sinfonia, MSC Opera, MSC Musica, MSC Orchestra, MSC Poesia, MSC Magnifica, MSC Fantasia, MSC Splendida, MSC Preziosa and MSC Divina, the parent and children have to be in connecting cabins.
On MSC’s other ships, they can either use connecting cabins or qualifying interior adjacent cabins. MSC defines those adjacent cabins as being on the same corridor and at the same assembly station with no more than three cabins between them.
There are extra requirements too, including the parent being able to access the children’s cabin, and balcony doors remaining locked for children’s rooms.
It’s certainly not a rule I’d want to try to memorise while booking. If you’re putting younger children into their own room with MSC, check the exact arrangement for your ship before paying.
P&O Cruises – 16 Years Old
P&O Cruises keeps things much simpler. Children under 16 cannot stay in a cabin unless somebody aged 16 or over is also booked into it. Guests under 18 must still be travelling with a parent or companion aged at least 18 on the cruise.
That means, for example, a 16-year-old could share a separate cabin with a 13-year-old sibling while their parents stay elsewhere.
It’s a particularly useful rule for families with older teenagers because P&O Cruises’ standard cabins can feel pretty cosy once you’ve got four people and the extra beds are down.
Cunard – 16 For Younger Children, With Extra Rules
Cunard’s rules depend on the ages involved.
Children aged 12 or under must be booked into a stateroom with somebody aged at least 18, while children aged 13 or over need to be booked with somebody aged at least 16.
So two teenagers aged 16 and 14 could potentially share together, but two children aged 14 and 13 couldn’t.
Cunard also says that passengers under 18 need to be accompanied on the cruise by an adult aged 18 or over, so again there’s a difference between having your own cabin and actually travelling without an adult.
Marella Cruises – 14 If The Cabins Are Next To Each Other
Marella Cruises has an interesting distinction based on where your cabins are.
If family cabins are next to or opposite one another, children aged 13 and under need an adult staying with them. In other words, children aged 14 and over can potentially stay separately when the cabins are next door or opposite.
For cabins that aren’t next to or opposite one another, guests under 18 must be accompanied. So if you’re travelling with teenagers and want them in their own Marella cabin, choosing the cabin numbers carefully could make all the difference.
That’s another reason I prefer booking a specific cabin rather than leaving the cruise line to allocate one when travelling as a family.
Disney Cruise Line – An Adult Needs To Be In The Cabin
Disney Cruise Line is much stricter.
Disney states that children under 18 need to be accompanied by an adult travelling in the same stateroom. Its terms also make clear that minors who aren’t travelling with their parent or legal guardian need a responsible adult in their cabin.
So Disney isn’t the cruise line to choose if your plan is to put a couple of younger teenagers into a completely separate cabin by themselves.
That doesn’t mean families can’t book multiple rooms, of course. You may simply need to officially split the adults between the reservations, even if your family chooses a different sleeping arrangement once onboard.
River Cruise Lines – The Rules Vary Wildly
River cruises are a slightly different story, because there really isn’t a standard rule across the industry.
Many river cruise lines don’t allow children at all. Viking and TUI River Cruises, for example, are adults-only and require every passenger to be at least 18, so there’s obviously no option to book teenagers into their own cabin.
Several of the river cruise lines that do welcome families are actually stricter than most ocean cruise lines.
AmaWaterways requires every guest under 18 to share a stateroom with an adult, while Avalon Waterways has a minimum cruising age of eight and also says under-18s must share their accommodation with an adult.
Uniworld follows a similar approach. Children can cruise from the age of five on most itineraries, but anyone under 18 has to be booked in a cabin with somebody aged at least 21. Riviera Travel has a minimum age of 12 for its river cruises and also requires every minor to share with an adult aged 21 or over.
A-ROSA is another river cruise line that’s well worth considering for families. I’ve cruised with my kids on A-ROSA SENA, and it’s one of the more family-friendly options, with connecting cabins available on several ships and even dedicated family cabins that sleep up to five on that ship.
However, while A-ROSA welcomes children of all ages, under-18s must share a cabin with at least one accompanying adult.
There are exceptions, though, and CroisiEurope is probably the most interesting one for families. On selected CroisiFamily cruises, children can have a cabin next to their parents or relatives from the age of five, subject to availability.
So if you’re used to ocean cruising, don’t assume the same cabin rules will apply on the rivers. A 16 or 17-year-old who could quite happily have their own cabin with Princess, P&O Cruises or Royal Caribbean may still need to officially share with an adult on a river cruise.
And because river cruise ships tend to have fewer cabins, fewer connecting rooms and very different family facilities anyway, I’d check the exact rules before choosing your cabins rather than trying to rearrange everybody afterwards.

Booking A Cabin For Your Kids Isn’t The Same As Letting Them Cruise Alone
This is probably the most important distinction to understand because it’s where a lot of the confusion comes from.
When a cruise line says you need to be 18 or 21 to book or travel on a cruise independently, that doesn’t necessarily mean your 17-year-old can’t have their own room while you’re travelling together.
Princess is the perfect example. Its general rule says under-21s need somebody aged 21 or older in their cabin, but the family exception drops that requirement to 16.
Royal Caribbean and Celebrity go even further, allowing cabins solely occupied by minors as long as Mum, Dad or their legal guardian is directly next door or opposite.
So when you’re checking the rules, make sure you’re actually looking at the policy for family groups occupying multiple cabins, rather than just the cruise line’s minimum age to travel.
Get Confirmation Before You Travel
I’d always recommend checking your particular cabin arrangement with the cruise line or your travel agent before booking, especially if your children are under 18.
And after seeing what happened to the Princess passenger who inspired this article, I’d go one step further and keep the confirmation.
If you’ve got an email from the cruise line saying your arrangement is allowed, save it somewhere you can access offline. I’d probably screenshot the relevant section of the cruise line’s website too.
It might feel slightly excessive when everything has already been accepted during the booking process, but being told “no” at a cruise terminal thousands of miles from home is not the moment you want to start hunting through terms and conditions on your phone.
The Princess family was ultimately allowed to board and enjoy the cruise they had booked, but those ten minutes of uncertainty could very easily have been avoided.
And with the rules varying so dramatically from one cruise line to another, I can understand why even cruise line staff occasionally get confused by them.
Just make sure that, when it comes to your family, you know the rules better than they do – because you definitely do not want to be stranded at port!
