To buy or not to buy, that is the question — at least when it comes to cruise line drink packages. To help you determine if one is worth it for you, we gathered the prices of drink packages offered on the most popular cruise lines. All it takes is a quick equation from you: divide the price of the package by the number of drinks you’re likely to sip per day. Note that some cruise lines don't offer unlimited packages and instead offer rates for beer or wine by the bottle. In this case, estimate how much you'll drink over the course of your cruise to determine if the price is right.
