This show never gets old. I took the family last night and it was still as amazing as it was 17 years ago when I first watched. Their performers have crazy ability. I would suggest watching the 7pm show as the lines aren't as bad as the 9pm show. The 7pm show pre-seats everyone 30 minutes ahead, while the 9pm show has to wait for the 7pm show to get out, cleanup before they get seated.
Also, don't think that the front seats are the best seats. Section 203-204 are great. You see everything above and on stage great. They offer drinks and some snacks. Mostly everyone gets popcorn. The bathrooms are outside. So use the bathroom before going in. You'll be bombarded with people who want to take your photo, so that means you'll be paying $40 per picture that you want, but they come in a Mystere photo holder. Overall it was a great show. It's been around for 20 years for a reason.
