Ok, well, maybe not so different besides the fact that we're dealing with bagged wine here. My wife and I have always been able to "smuggle" a boxed wine on board the Carnival ships (not allowed, per the rules, of course) which was taken out of the box. The bladder of wine doesn't come up too well on the x-ray machines, I'm told, and have since learned is probably true. Every time our luggage arrived in our rooms, the bladders of wine were safe and secure inside. Anybody done this on RCI recently? We plan on doing it with a bladder of red, but still purchase drinks at dinnertime and randomly from the ship. We primarily fill a glass up at night, then go outside to a railing (last cruise we had a balcony, which was great for this) and make a romantic evening out of it. I seriously doubt RCI would kick cruisers off for bringing their own alcohol on board, as long as it's not excessive, but don't want to risk it if anybody has had to walk the plank or spend the cruise in the brig! FYI: you can buy "premium" boxed wines in the store, so remember that this isn't the bitter, not so elegant tasting wine, when you respond saying "Boxed wine, eeewww!" They actually have some decent stuff now.
