I have to say that this might have been one case where it wasn't worth the HUGE hype. I had played it up so much in my head that there was no way it was going to meet expectations, and it ultimately didn't. I'm not going to spoil the show for anyone, but you will see some amazing things - and don't read reviews about it. Just go, especially if you're a fan of Cirque. Supposedly the Las Vegas shows are the ones that are the best.
I'd probably also recommend the 7:30 viewing rather than the 10:30 one I went to...I was trying really hard to stay awake but it was hard during some moments. They do a good job though, of combining some incredible human feats with humor.
I'm glad I went, but not glad I spent over 300 dollars on a pair of tickets.
