It is a special party like the Mickey's not so scarely halloween party and the Mickeys very merry christmas party. Children and adults as well as the Disney Characters dress up in pirate or princess costumes. There are really cool dance parties and attractions set up throught the Magic Kingdom which is where the event takes place. There is a very very cool parade that starts out with the princesses and their princes and ends up with all the villians and pirates. Jack Sparrow is there and the characters, dressed in Pirate attire, are available for pictures. When you enter, they give you a velvet pouch and they have lamp posts set up throughout the park marked with X's. The children (and adults) go from station to station based on the map which is provided. You get candy and loot at the stations. All of the rides are open and the wait is usually minimal because it is a ticketed affair. We LOVED it!!! There is also a very nicke fireworks show in front of the castle. Definately worth it.
