Magic Kingdom at Walt Disney World, Lake Buena Vista, Fla. (16,640,000)

The Magic Kingdom is the heart of Walt Disney World, where costumed Disney characters roam the streets and Space Mountain rules the ride roost. Cinderella's Castle, based on the turreted Bavarian castle Neuschwanstein, is a classic.

It may be close to Mickey and Minnie, but those who dare to wander through the halls of Skull Kingdom’s haunted castle at night will vouch for this place’s high fright factor. During the day, there are less frightening, guided tours of the castle aimed at youngsters – children are even given their own flashlight for extra security!
