This is a pretty interesting show. I personally believe in hypnosis, but have never been hypnotized myself. I think it just doesn't work on me.
There will be real audience on stage, at least they seem very real to me when they were leaving the theatre. The performer Marc Savard is pretty interesting, he makes the show fun to watch even though I was wondering if the whole thing was real or not the while time.
This is the first hypnosis show I have ever seen, not expensive, and it gives you a huge discount on a small magic show, very good deal. If you have nothing to do in Vegas and want to watch a simple show, this will be a fine choice.
