My daughters and I had an unusual experience with these mystery passes a couple months ago. As we were about to get on Indiana Jones a gentlemen asked my oldest daughter if we would like to skip the line. The man was older, had grayish long hair he wore in a pony tail. He reminded a little bit of Doc Brown with a few more pounds. She said sure because she thought he was going to give her some unused fast passe. Next thing we know this guy takes us to the front of the line, shows the pass, the cast member asks how many people are with him and off we go. He was really into showing us all the hidden mickey's, Eeyore, etc. When we got to the loading area we were allowed to use the elevators and walk directly to the loading area. After the ride the guy offered to take us on Space Mountain but we had to leave. If it was a special assistance pass you sure could not tell from this guy. He had a real spring in his step. On later trips to the park I spotted him again taking other folks on rides. A most unusual experience indeed.
