I am reviewing all the Cirque Vegas shows, so I will add this paragraph comparing each one. I have seen each one twice (and saw LOVE 3 times), so I feel confident in my ranking. My ranking would be 1) Ka 2) Love 3) O 4) Mystere 5) Zumanity 6) Viva Elvis. Ka is the most technically complete, with a storyline, amazing stunts, creative images, stages rotating on axes, etc. LOVE is the most fun and a very close second place. O is the most beautiful. Mystere has the best stunts and is most "traditional". Zumanity is the sexiest, but stunts are just okay. And Viva Elvis could be sooo much better. You can read my other reviews for more info...
You need to have the proper expectations when you go see this. Don't expect a strip club or Crazy Horse style experience, and don't expect the great quality of stunts you'd find at some of the other cirques. It falls somewhere in between. BUT it's a good show. It's sensual and humorous and a fun time. Make sure to get there early to watch the pre-theater interaction with audience members.
All the seats are good, so no need to pay extra. I've sat at the top and still was able to see well. The fishbowl scene was a highlight as well as the tub scene and the contortionists.
