We saw a Sunday show at 9:30pm. Don't know if it was me being a Cirque-aholic/snob that I couldn't really enjoy the amazing artistry and stage production, or if it was Sunday and the vibe of the crowd was: "I'm too tired from partying the night before" or "I should have gotten tickets for O at Bellagio".
If its your first Cirque show....be amazed.
If you're a Cirque groupie...it will be a 1.5 hour show that resembles what you paid for in other Cirque shows.
My partner thought Zark was annoying.
