We really enjoyed the tour. It was 3 hours long. I'm not familiar with Wayne Newton, but I learned a lot of cool facts about him. Our tour guide, Mamo, was awesome. I wish I could have splurged on the diamond tour, but the platinum tour was a good value.
There were just a few areas that need improvement. As another reviewer suggested, it would be beneficial to have informational plaques near the cars or at least name plates identifying the make, model, and year of each car instead of relying on the tour guide. Also, there was heavy realiance on the videos. We felt somewhat forced to watch the videos and then didn't have much time to actually view the displays.
My mom is a huge Wayne Newton fan. She loved the tour and said she would do it again. The tour was good for me. I'm glad I went.
