Keep in mind that cruises frown upon bringing alcohol on the ship. I know at least Royal Carribean considers the discovery of alcohol in your room as grounds to kick you off the ship at the next port of call. I don't know if they'd actually do it, but the threat is there. They make a lot of money off the booze they sell on the boat - they don't want you drinking your own. Maybe they have some way to store the stuff you buy until the cruise is over. Just something to be aware of.
