Most cruise lines require a stateroom occupant to be 21 years of age or older to book a cruise.

For families travelling with children or young adults, it is possible to book two cabins. The rules vary from one company to another depending on the age of the children. If the children are young, it is possible to book a cabin communicating with the parents’ cabin or adjacent to it. Age restrictions for balcony cabins are imposed for safety reasons. A few companies will allow the cabin to be a little further away for teenagers or will not impose a rule for young adults 18 years of age and older.

Some companies require a consent form signed by parents or legal guardians for youth aged 18 to 20 who are travelling with an adult 21 years of age or older who is not their parent.

Some companies also have a curfew policy for younger travellers. They must be accompanied by an adult to circulate on board after a certain hour at night.

Generally, it won’t be possible for young people under the age of 21 to consume alcohol on board a cruise, even if it is allowed for those 18 years of age and older in their country of origin. Some companies will allow it, in international waters only, if the parents or legal guardians sign an authorization form.

It is important to check the specific policies of the cruise line you plan to travel with, as they may vary.
