DRS from what I found out during my recent trip is that you can call the line prior to sailing and have a setup. We did the liquor setup and payed 40 a bottle. As far as beer goes.. you can pre order itand pay I belive 4 a bottle or wait till you get onboard. They have a special which is 6 beers in what looks like a football helmet with ice for 25 dollars, 45 if you want to keep the helmet. During the whole trip I had seen numerous helmets waiting in the hallways empty. Just get onboard order the helmet special and stackem in the room. Have room service bring you ice. I had 2 tubs of ice delivered each day to keep the drinks cold.
Thats what I would do, instead of the sneak on routine or paying 100 bucks a case.
