It's a very cool tour. I actually enjoyed it a bit more than Keys to the Kingdom, but that was undoubtedly due to the phenomenal tour guide we had. We only did one ride, Soarin', and went in the VIP entrance from backstage. When we did the tour (2014) we got to go upstairs in the Imagination Pavilion. That's where the DVC lounge is now, so I suspect that's no longer a part of the tour. Also went to the VIP lounge in both the Living Seas and Mission Space. VERY COOL!
I'd gladly do it again!
