Believe me, Moviepark is not worth it anymore, the demolished a rollercoaster (URL), but Europa park is a great park, and if you can afford it, try the colloseo hotel located near the park, a great themed hotel with a greath bar at the top of it.
Holiday park is not far away from EP, the park itself is not very good, but Expedition Geforce is an incredible coaster.
Heidepark is some more away from EP, the park is very 'german' in the theming, it has a airtime woody and from next year they have a kind of 'Rita' copy (Desert Storm)
If you are travaling from EP to Heidepark an funny sugestion is to visit Legoland Germany, not very special, but who didnt play with lego when he was small, when you walk there you just get happy (visit the Link for a picture TR (in dutch) from a few friends of our last visit to legoland)
