nobody is gonna care what you do in regards to taping. DMB won't care, the cruise ship won't care and bud light will have no fucking clue what you're doing. i can guarantee you it will be a free for all on that ship.
if you're lucky enough to get on the ship, plan on taping. its a cruise ship for gods sake... there will be video and still cameras everywhere. this is one situation where you can get away with pretty much anything, anywhere.
