What the Rules Look Like
The common North American shape: an under-21 guest needs a qualifying older guest in the same cabin, or in some cases a connecting or adjacent cabin booked together. Carnival generally requires guests under 21 to travel with a qualifying relative or guardian age 25 or older, subject to its cabin rules and listed exceptions; most other majors use 21 as the qualifying age, with their own exceptions for married couples and family groups.
On departures from Europe, Asia, South America, Australia, and New Zealand, some lines permit unaccompanied guests from age 18: which is why a 19-year-old's trip that can't be booked out of Miami can sometimes be booked out of Barcelona. Which lines, which sailings, and which cabin arrangements qualify is exactly the homework we do before you book.
Grandparents, Aunts, and One-Parent Trips
A grandparent can usually take a grandchild if the booking satisfies the line's age and cabin rules, and if the adult carries every authorization and document the line and itinerary require. Lines commonly ask for written parental consent for a minor traveling without their parents, and divorced or separated parents traveling with their own child are often advised to carry consent from the non-traveling parent. Requirements differ by line and destination.
Get the cruise line's current minor-travel requirements in writing before final payment, and check them again before departure. We can point you to your line's current requirements and build the checklist with you: the traveler confirms them with the line and the relevant authorities, because those are the parties whose word counts at the pier.
Accurate as of September 2026; cruise-line policies change, and your line's own documents govern. When in doubt, ask your line, or ask us, which is free and comes with opinions.
