I have seen posts like this here and on the Cruise forums for a long time, and each time I ask myself, "Why would people want to lug all of their luggage AND cases of water/beer/wine on a cruise ship?"
You have paid a good amount of money for the cruise, you know you like to drink, why not save up before the cruise and put the money towards the liquor bill? Especially now with the extra baggage fees on the airlines.
I just don't get it.
