Ok here is my question...I am 20 years old and I have cruised with Princess on the Grand one time before with my fiancee, who is 23. I never had a problem getting served alcohol on the Grand since our bar tab was on his room card...my question is, I am going on a cruise with only my best friend who is also 20, on the Carribean Princess. Since no one in our cabin will be 21, when our card is scanned, will the computer automatically not allow us to purchase alchohol?
I believe they can tell just by looking at your card that your are underage. The card is marked to make it apparent, so the server can say to you when you place the order they that can't fill it, rather than waiting until they've returned to the bar, possibly actually made the drink, to discover this fact.
They are strict about adhering to the drinking age.
