It used to be about 7-8 drinks to break even. That’s fancy coffee ,nonalcoholic and alcohol.
So if you think you will drink more than everyday , it’s worth it .
There is a cap on the price,I think it’s $14 but drinks rarely get over that.
U.S.Dollars onboard and 18% gratuity but with the drinks package it’s included.
Beer about $8 cocktails about $10 ,mixed drinks about $12 that’s USD .
I’ve done a few Royal Caribbean cruises and I have never bought the drinks package.
The first few days people drink like a fish and then it tapers off .
