Well, we went to WDW 6 years ago shortly after Expedition Everest opened and were totally blown away by the entire experience from the moment you go to Asia and see the towering over everything to the moment you exit the ride. Course the Yeti (back when he was fully operational) was amazing to say the least. But even that experience was just a little better than the experience of the Tower of Terror. So, for me, Yeti is what separate Expedition Everest from the Tower of Terror. So, for me, when the Yeti stopped working I had to put Tower of Terror on the top of my list. Don't get me wrong, Expedition Everest is an amazing ride still. But I just gotta put Tower of Terror on the top of my list.
