So I’m going on a cruise to Alaska with my family in July-August time frame. I understand that cruise ships over the drinking age is 21. All except for one person is over 21 years of my party (my little brother is 20). We are in a place where the legal drinking age is 18 +, so we’re very used to the whole family for a drink social. Just curious if anyone was able to bend these rules on cruise lines, especially the princess and / or Holland America cruise line.
