I was recently given free tickets to this exhibit. The Luxor definitely needed to do something about their ticket counter because it took us 25 minutes at 4 pm on a Wednesday just to get in. There was a man working the counter that was in charge of the audio programs and he stood there talking to the security guard about rock bands the entire time the other employee was busy with a very long line of people wanting to get in. Ugh!
I did find the exhibit interesting and as many other reviewers stated, the recreations of the staircase and cabins were nice. However, even by Vegas standards, $56 for two tickets (if I had had to pay) would not have been worth it. After the 20th display of some bolt or valve that was from some mechanical part of the ship I became a little bored and did not mind when we reached the end.
