I too wondered how to do it. lol At the port of Long Beach, a few years ago, a baggage handler mentioned he could make sure that 'everything in the bags would make it onto the ship' as he put his hand out. Had I had any alcohol in my bags at THAT time on THAT cruise, I would have taken him up on his offer... However, I did not. I think next time I'll just do the 'water bottle' method and hope that it works.
