What places have you been with your kids...?

...or what places would you like to visit around the world or across the states. I just want a general list of fun places to take kids from your experience or places you would like to go. Like for example I'm going to take my kids to Disney world one day (Orlando, FL), Lego Land (Lego land, CA), HERSHEY'S CHOCOLATE WORLD (Hershey, PA), and The Crayola Factory (Easton, PA). Thanks for any ideas =)
