HM's @ Expedition Everest
During our visit earlier this month we were given a tour of Expedition Everest and the CM, Brandon (See Cast Member Appreciation Thread on him). He pointed what he said were a couple of Hidden Mickeys, which I was unable to get a picture of (I had to hang on and didn't have a free hand). When we first left the station and were clicking up the track there is a small arch that has prayer flags hanging in it. He said to look up inside towards the left and there was one there.
The next isn't really a hidden mickey, it is a imagineers addition in decor. When waiting in the que's he pointed out in the Fast Past line in the 'offices' there is a book shelf that has a bunch of books on it on Everest. Mixed into the books is a book on Disney. :wink:
