I love the Lion King show, too. I haven't seen it in a couple of years, though. So my favorite would have to be the Beauty and the Beast show at MGM. It is a must see with my girls (5 & 8). I get goosebumps everytime. I don't know if it is the show or the look on my girls' faces as they watch the show that give me those goosebumps.
The quality, professionalism and incredible voices of that cast was so far above the rest. They drew you into the show as if you were part of the Festival of Fools crowd.
Lion King show is lots of fun and we really enjoy it's creativity, but I can't think of another show there that isn't just dress up acting. I guess Fantasmic is a show......I was really impressed with it's technical accomplishments.
