I've purchased the $1 bottles of booze that are the size of the kind you get on an airplane. I bought many and stashed them thoughout my luggage. I figured, if any were "caught" I can turn "those" in and still get away with sneaking some others on board anyway. In the end, they all got through, and I was giving them away my last nite at dinner because I had plenty left over. lol.
I also poured some in a six-pack of water bottles still shrink wrapped. I got one bottle out of the shrink wrap at a time, filled in and replaced in. Taped the bottom with clear packing tape--it looked completely unopened.
Does it seem like I'm a pro? lol
I guess I've found the booze cheaper vs. buying on the ship. And then again, when you already have a bottle of vodka in the house, it's cheaper than buying more at the store!
