I always end up having to DRAG my kids out of Innoventions - they spend hours there! There is so much to see and do in it. Also it's fun to go into Club Cool (although my kids miss the frozen cave man) and sample all the sodas.
Yes, there is a lot to explore. Waiting for Soarin', you can hang out in the Land or go see Figment or the Seas. For Test Track, you can do the other side.
Anyone else miss Body Wars? Sad, wish they could get a sponsor for that pavillion; it's been years.
