You didn't mention which ship you are going on. If tips are automatically deducted from your sail-and-sign account at the end of the cruise, you won't need to bring cash for tips (though you might want to set a little aside because you will no doubt want to tip above the recommended amounts for outstanding service).
It's possible you will have to bring cash for tips. If so, set this aside in an envelope in the safe and don't touch it
until tip night.
