You also tip the assistant waiter, (usually half the amount of the waiter). You tip the waiter also. There is some debate about tipping the maitre d, most agree that unless he does something above and beyound the normal duties, that it its required. What tips does that $6.50 cover, do you know? I did hear something about this, but don't have all the details. BTW, cruised on Ocean earlier in the year and absolutely love that ship, enjoy.
