I was lucky enough to find a deal on www.Travelzoo.com. I bought my ticket for $11 (w/o tax).
The production, of course, wasn't as grand or super creative compared to those of Cirque de Soleil; but I was impressed by the acrobatic's energy, humor, and enthusiasm throughout the show.
I recommend this show to those who can find a coupon/deal. I probably wouldn't want to pay $56 for general admission.
Overall, it was a good show; I enjoyed my time and I had a few laughs.
