This was very interesting and the exhibit is well organized. I'm basing the three stars on value for the money (even though I got a good Groupon deal), and the fact that it wasn't really worth the hassle of going to the strip, parking, walking miles through the casinos to find the place..
If you enjoy walking around the strip and through casinos anyway, and if you do find this sort of thing interesting, I do recommend it.. If not, just look at the pics posted here and watch some videos. Save your time and money =)
