I'm going on a 7 day cruise in august. I'll be boarding the ship at the age of 20 and turning 21 mid week. I understand that Carnival has some policy that won't let you buy drinks if you board while underaged, but my parents and friends will be with me! Isn't there some type of exception? Couldn't i just go to the pursers desk with ID and have them alter my sail and sign card so that I can buy drinks? I would really like to order champagne or something during my birthday dinner.
