Japan = I love the giant feudal era Japanese castle, and all the cool stuff and weird food they sell at the big department store.
Morraco = I love this area because its so diffrent, and the archtecture is amazing, I especaly love looking at the tiling in the fez house.
Mexico = Mexco has the coolest layout, you enter a Aztec pyramid into a mexican village at night time, and also I love the Three Caballeros boat ride.
German = Defiently has some of the best shops in one area, you can buy nutcrackers, playmobil, coco clocks, and eat a very cool resturant with live entertainment (sadly missed the reservation 2 times though.)
