Le Reve is *Not* a Cirque show. Similar, but not the same.
It was originated especially for Wynn by Franco Dragone, who directed the Cirque shows, so it has a lot of similar elements. It's a truly spectacular show and I highly recommend it.
Penn & Teller are good as is Blue Man Group. But, I'd pick LeReve out of those three.
Another show that is a bit similar to Blue Man Group is
Jabbawockeez at the Monte Carlo. Having seen the Blue Men several times, I actually enjoyed Jabbawockeez more. They both have the element of "disguised" faces, but I just liked the humor, music, and dances of Jabbawockeez more than the antics of the Blue Men. BMG is unique and extremely creative , though.
I noticed that LeReve and Jabbawockeez were available on Tix4Tonite yesterday.
