Drinking age for carnival cruises!?

The drinking age on all cruises departing US ports is age 21, and that does not change in international waters or on the ship while in port where the drinking age on shore is under 21. Nor does it change or become "flexible" because you are close to age 21 and/or married. Crew members who knowingly serve a passenger under age 21 are subject to immediate dismissal. Now, if your husband uses HIS key/ID and buys a pina colada and hands it to you away from the bar, and if he is careful not to purchase 2 drinks at the same time, you will probably be able to have that drink. However, you would be risking the bar man's job, plus place yourself in the position of possibly being removed from the ship, bag and baggage, with no refund and no apology and with the need to find and pay for your own way home. The days of underage drinking being winked at are long gone, and the ships are very vigilant these days. So -- how about enjoying that pina colada on shore instead?
