1.Most cruise lines will not allow women to sail in the third trimester of pregnancy; you must typically be 24 weeks pregnant or less on the day of disembarkation in order to cruise.
2.Babies must typically be at least 12 months old for trans-ocean, "exotic" or world cruises and 6 months old for all other cruise destinations (with some exceptions). Some adult-oriented ships don't allow children at all.
3.Note that on most cruise lines, passengers must be at least 18 years of age in order to travel on their own, without the accompaniment of a parent or guardian. Read up on such age restrictions in our Cruise Line Age Policies.
4.The DHS requires cruise lines to provide a final passenger manifest at least an hour before departure. The deadline is one reason why cruise lines have encouraged passengers to provide their personal information well in advance of sailing via online check-in.
5.Deposit and Booking Requirements.
6.Note that cruises can typically be booked as far as 18 months in advance to as little as a week ahead of the scheduled sailing date. Lines do not require that you pay in full when booking. Rather, an initial deposit is required, which typically ranges in the amount of £550 to £1,500. The balance must usually be paid one to three months in advance of the sailing. Deposits are normally fully refundable if you cancel your sailing before the final payment is due.
