Finally got a chance to get this place off my bucket list for Vegas. Set aside at least 3 hours if you want to take your time and enjoy the museum. The cashier at the front said it took 1.5 hours but I was only on exhibit 4 of 10 at that point. It takes awhile to deconstruct the densely packed information at this museum. Each exhibit has about 10 videos and numerous artifacts.
The one cool part was the video room where it feels like you're watching an atomic bomb explode.
The negative part is that I was rushed out.
The museum would do well to offer visitors a free next day pass for those arriving around within 2 hours of closing time.
