Walt Disney World Resort, Orlando

You have two options: one day passes cost 50$ for adults, 40$ for children, but you can't see much of the park in a single day. So, there are special tickets for 4 to 7 days admission that range from 200 to 300$ for adults and 160-256$ for kids. I needed a week to see it all: it's divided in 4 parts, with different themes: the Magic Kingdom, with the coloured Cinderella's castle, the Epcot (Experimental Prototype Community of Tomorrow), with attractions such as the Spaceship Earth, the Disney-MGM Studios and the Animal Kingdom, actually a zoo. Good luck!
