I agree with Penny also-I always use the pre-paid gratuities, and almost always add extra tips to the waiter, his assistant and the room steward. Anyone who has to straighten up after me deserves a little extra. I always thought that the highest tipped person on the ship would be the Matre-De (sp?). He usually gets only a dollar or two per person, and on the larger ships with above 3000 pax, he makes out like a bandit each week. If you figure he gets tips from 85% of the pax, he makes upwards of $2500 per week in tips! I'd even wear a tie and sport coat for that kind of money per week!!
