I want on a cruise for Spring Break in March (right after I'm on a Boat came out) and damnit I wanted to kill all the sorostitutes running around screaming the lyrics.
But I would recommend bringing a camel back for liquor. It allows you to easily carry a ton of liquor around and stays cold for a lot longer than anything else. Instead of mixing drinks every 20 minutes, do it once per few hours.
If you don't want to drink it straight, you can either buy a Coke pass ($30ish) and get cokes/sprites at bars or they have free juice bars (lemonady, fruit punch, etc) that you can go to on the top decks. Also, we smuggled beers on the boat by putting them in Coke cases and chick's purses (only time I've ever liked the big ass purses they carry, one of them actually fit a case).
