This exhibit was interesting and intriguing. I spent well over 1 1/2 hours finding out the stories behind some of the best photographs from National Geographic. The only thing that was a little so-so to me was the fact that some of the photos didn't have the history of the actual photo subject and just talked about the way the photograph was taken, so there was some interpreting that one would have to do. I guess, in a way though, it caused you to want to do more research on your own afterward to find out the rest of the story. There were also video monitors showing an interview with the head of National Geographic and the photographers for the top 8 photos placed between the two photos they were discussing. It was also very interesting to see the "near shots" taken before the famous picture was taken.
Probably not the first thing that people are thinking about when headed to Vegas, but if you want some entertainment that you can actually talk about later, I'd highly recommend stopping in at this exhibit!
