Normal
Just to clarify, while the $10 per day is "optional" it is customary. You don't want to "stiff" the service personnel. The $10 per day covers your waiter, assistant waiter, cabin attendant (steward) and the head waiter. It is so much easier to just leave it on the ship board account and let the cruise line divide it up. I usually tip a little extra in cash too because the service is always great.
