Tracy,
Soarin' is a hang glider simulator, and you "fly" over an Omni-type movie screen showing scenes in California. It is multi-sensory--you not only feel the motion of the hang glider, there's also wind in your face, the scent of grapes as you fly over a vineyard, etc. It is breathtaking--I've never experienced anything like it. I should also note that I am EXTREMELY prone to motion sickness (I frequently have to close my eyes during rapid motion parts of plain old Omni movies), and I had no trouble at all on Soarin'. It's spectacular--one of the very best attractions of either park in DLR.
