I don't drink wine/champagne, but I do pack a couple of "tester" bottles (the very tiny ones, one for each night) of vodka just so I can have a cocktail while I am getting ready. I have seen/heard people bringing on bottles of booze/beer ect. We were on the Mariner in 2006 were a young man put himself overboard during the night and was never found. The group had video taped themselves drinking in their cabin the night before it happened. They had brought on many bottles of booze, very sad. My boys were 12 at the time, it was a very
lesson learned. If flying I would also be concerned that the bottles ect. would not make it in the luggage??
