Tower of Terror has a pretty amazing queue. The details are staggering, and it makes you feel like you are walking into a real location rather than a ride building.
I was wildly impressed by the queue at Expedition Everest as well, because it felt educational, because of it's heavy basis in reality. The whole vaction lines moves slowly, but with Everest, it actually moved to fast. Soon enough we were at the trains and I was a tad disappointed I didn't get to see more.
I was also thrilled to see that they tried as best they could to replicate the highlights for the FastPass line. I went back on a FastPass later and was very impressed that they took the time to make it a better experience than most FastPass lines.
