The drinking age on all U.S.based cruise lines is 21, even when sailing international waters. (Under special circumstances, some cruise lines allow 18 to 20 year-olds to purchase and consume alcohol with a parent's consent.) Regardless of the policy, you should never buy a drink for someone under 21.
