We used a 40% off coupon from the American Casino Guide. Otherwise, the cost would have been $50 for the two of us. That would definitely be too much money.
Overall, it was okay. Most of the wax figures didn't look as much like the celebrity as they should have. I thought the best were John Wayne, Princess Diana, and Lucille Ball. There were two or three that I didn't recognize.
We stayed at The Venetian so the museum was convenient. It kept us out of the casino for a couple of hours and saved us some money since we weren't gambling.
