Magic Kingdom is fine if you are with your kids but you can skip it if you have been to Eurodisney. The only thing they don’t have their is Splash Mountain. MGM is for moviebuffs, since it offers lots of probs from films and the Indiana Jones Stundshow is worth watching.
The “Animal Kingdom” ranks as my favourite Disneyparks out of all four Disneyworld themeparks. There is a lot to see, the attraction don’t get stuck all the time and there is plenty of usefull informations even for adults
Epcot Center is very interresting, the rides are quiet old, expect the Crash-Test Dummie Race, but the different countries are very entertaining to visit, and don’t miss the movies about Canada, China and France, they are fantastic.
