Test Track at Epcot is bloody amazing, probably on the same level as Everest. So many car displays and videos and things to look at, it's almost not that bad to wait in, provided you don't get stuck in the standby line for an hour and a half. :roll:
Tower of Terror is pretty cool too, nothing beats walking through that immaculate and intricate lobby on the way to the library and into the boiler room. Haunted Mansion is kind of the same way but less elaborate.
And Space Mountain I like, even though it's a pretty boring queue. I like the music a lot, and the space theme. It's definitely one of my favorites and I love waiting in it.
Bizarro in SFNE has the best dried-up gum-themed queue I've ever seen. :lol:
