This All Night Disney Party is at the Magic Kingdom right? It seems like a cool idea. They had a little one of those Disney Parties with some of the characters when I went to Hollywood Studios.
Yes that is why I really like Epcot because of the different countries. They have awesome rides too but I like the Rockin Roller Coaster and the Tower of Terror better at Hollywood Studios. The buffet is right in the center near the castle. I think it is right in front of adventure land I think or right near the ice cream parlor.
