"(I would recommend going. It's really interesting to watch and the show isn't terribly long (if your sister's worried about wasting time).
The music is fun and the stunts are really something. I think the only part that bored me a little was the chair guy.
I really enjoyed the chinese yo yo girls.
It was fun, make her go! Plus, how many days are you going to be there? I'm sure you'll have plenty of time to fit everything you want in.)"
I totally agree. Please don't expect TOO much. How Jenrose put it is correct. Think of words like "interesting", "fun", "enjoy", don't think of it as "out of this world awesome, unbelievable". I don't know WHAT I expected, but I guess "magic" or something beyond capabilities. We were terribly dissappointed, but I think only because of expecting too much, because of all the commentes like "unbelievable" , "indescribable" etc.
All that said, I think you really should see it. I don't think it's wasting Disney time, it's another fun thing you can do at Disney. Just make sure you don't expect too much and then I think you'll be pleasantly surprised and like it.
