How strict are they at the bars on Carnival Cruises?
The various cruise lines are very strict, as other posters have indicated. They need to be very aware of the law, liabilities and the potential to have their licensures revoked. To purchase any drinks on board (anything carbonated or alcoholic costs money), you will need to present your Sail and Sign card. Your card will most certainly be either color-coded or digitally encoded to indicate that you are under 21. So, you may not get ‘carded’ per se, but your card will likely give you away. My suggestion: stay away from the ship’s bars. They take underage drinking very seriously, and you could potentially risk a penalty up to being asked to leave the cruise. A few drinks is not worth ruining your vacation over! You could try your luck on shore, but be careful there as well. Remember that you are in a foreign country, and unless you know for sure what the laws are, you could be taking a BIG chance.
