Your personal staff onboard are all working extremely hard for you while you're enjoying your cruise.
Usually at your discretion, the cruise lines will provide a recommended daily amount to allow for tips and, with your permission, may often automatically add the gratuities to your shipboard account. This amount covers your cabin steward and the waiters and assistants who have served you in the main dining room.
Just because you're being automatically billed doesn't mean you don't have control as you can adjust the amount up or down by paying a visit to the Purser's Desk. You may also have the choice of pre-paying your gratuities, along with your final payment, at the time of booking.
