Why not just call beer BEER, and wine WINE, and liquor LIQUOR? Is there some reason for the code words?
BTW, a co-worker of mine recently booked a 7-day on the Norwegian Dawn for this coming January. He asked me for advice on the cruise, and when I asked him if he had gone to NCL's website his reply was "yes, but their website pretty much sucks". And that is a direct quote.
