Well....I don't know whether my advice will help, as my children are nerds like their mother, so we took them to Epct. The first time we went with children (2006), my daughter was 6.5 and my son was about to turn 5. They loved Epcot. The climbed on the fire truck (like they can't do that at home - I'm a volunteer firefighter), they made paper, they loved Living with the Seas and The Land. World Showcase allowed them to color masks and talk to people of different cultures....they ate it up! It's still their favorite park I'm happy to say (and mine, too, of course!).
