My daughter loves Stitch (it's her mother's favorite character as well), but this is the only ride/show that I've ever felt that I would have to exit out of with her.
In 2010 (age 5) she was so excited, and thought it would be fun and cute like the movie! Nope. She freaked out. I tried to calm her down, but she was screaming and crying (this from the same kid who didn't bat an eye at Everest). I thought we would have to leave the show because she was getting so hysterical. I literally had to carry her off the ride (when it was over) and she wouldn't let me put her on my shoulders until we'd made it almost to the Teacups, where we stopped in Cosmic Rays to get a cookie treat to calm her nerves (she loves Cosmic Rays)...
In 2011 (age 6), I guess she'd forgotten about it from the previous year, and really wanted to do it. So, reservations aside, we went. Again, she freaked out. Though not as bad as 2010, I still had to carry her out of the show.
In 2012 (age 7), she seemed to have forgotten about it again! She insisted we go, even after I reminded her that it scared the pants off her the previous years. So...again we went. This year's freak out wasn't as bad as previous years, but she still was overwhelmed by the ride, and not in a good way.
Dunno if we'll do or skip this coming trip. I'll leave that up to her.
