I don't know about you guys, but AE scared the cr*p out of me, almost literally! I definately agree that the bars were to keep people from bolting. If I could have, I would have! I do not fright easily...but the combination of all the effects, the wispering on the neck, the mist (felt like light spitting on your ear) worked! All the "it's just Mickey Magic" mantras I said to myself during the event didn't help. I was very surprised this attraction was a "Disney" attraction. Now, on the flip side....Stitch is awesome, and I could see the same experience being not so scary because it's stich. I really wanted to see this attraction as my daughter is a Stitch Freak, I would have never taken her on AE but I would go on Stitch's Great Escape in a heartbeat.
Final note, when we were there in 1994, I asked my now ex-husband to go on the ride first to check it out for me and my then 6 year old son. He came off the ride, came to the bench we were waiting on and said, "It wasn't bad, Zack (my son) will like it!" Needless to say that's one of the reason's he's the Ex. And my son did agree AE was good, after about 2 hours of consecutive Small World rides.
