No, it's not a real pirate ship. And, no, Hook and Smee aren't with you on the boat. There are two pirate captains, both named Patch. They're really funny. For dessert, there's usually a cake, ice cream treats (usually in a cooler in the back), bagged cotton candy, pretzels, lemonade. That's all I can remember.
The seating on the boat is split into two sides, with the odd numbered seats being closest to MK.
