The best show in Vegas. Period.
We've seen it 4 times, and will see it again. If that's not an endorsement, I don't know what is. You can youtube the individual acts and see them online, but you can't get the true feeling for sitting within feet of the stage, watching these amazing athletes/gymnasts/artists perform close enough that if they screwed up, they'd end up in your lap.
Tip: If you're offended by racist, sexist, political, or other types of innuendo/humor, don't go. If you've purchased a ticket already, give it to me instead.
