The Pirate Cruise is for kids, and it leaves the Grand Floridian in search for buried treasure! They make several stops while looking for the treasure, and a snack is provided for the kids. At the end, they divide up the treasure and all the kids get a bag of loot!!
My DD did the cruise once, but she said it was too hot! (It was on one of our July trips) She really had a good time though, but her favorite is the Alice in Wonderland Tea Party!
When you check the kids in, they have to put on their life vest and pirate "hat"!! It really is cute! I think it costs about $20 or so.
