One of the original Cirque shows in Vegas.. and one of the better ones. You don't need to line up unless you really want to because, c'mon, you've got assigned seats. There will be the usual Cirque performer that'll be causing some trouble in the theater so you should probably come in about 10-15 minutes before the show for that. He's fun!
There are many different acts/scenes as it moves from one stage to the other and they're all very good. I loved almost all of them and that's usually saying a lot. The baby character is always a nice comedic relief. They do a lot more audience participation in this one and that's always a plus. Love seeing people's reactions and I'm sort of surprised they get away with some stuff, haha.
KA is my favorite but this is definitely my 2nd :). MUST SEE!
