Our family of 5 went on my son's 10th birthday. We purchased the 2 for 75 (plus additional fees for certain shows). So what it averaged out per ticket ($65) for very good seats, I was satisfied with and felt it was worth it.
What made the show exceptional for us is that when Criss Angel ran up the aisle, my son stood up and got to shake his hand. A few moments later when he ran back out handing out pieces of paper, he handed one to my son. Even though his paper didn't have the symbol on it, it made his night and his 10th birthday unforgettable!!!
I had heard reviews that weren't so great but my whole family love his show and that's what my son wanted for his birthday. Maybe having lower expectations made the show better for us. We all had a great time and laughed a lot. My son walked out saying he would never wash his hand again and went straight to the store to purchase a Criss Angel official magic kit. He has been practicing since!!
