How did you smuggle YOB on the cruise ship??
You don’t want to know.
We packed wine bottles in the luggage.
Also used large plastic flasks for hard liquor.
Did it many times....never broke a wine bottle and the cruise line never knew.....as far as I know.
Also another trick when you hit a port is take a large water bottle in your backpack, buy some vodka and fill ‘er up....any search getting back on the boat it looks like a bottle of water.
