There is a Pirate Night Deck Party...buffet with nice desserts
As for driving, dropping off.....you pull car up to terminal in a designated area, unload your passengers and luggage....the porters are there to handle the luggage (tip them accordingly...for 4-5 bags, I give $10),which will magically appear at your stateroom door by 2pm usually.... then you can drive a short distance to the parking lot....the attendant will charge you $10.00 per day....you then park the car, with a short walk back to terminal...
Word of caution: Do not leave ANY food items in your car.....you will have ant infestation of epic proportions....
