Really enjoyed our visit to this museum. Got a really good better than 2 for one Groupon deal, which was a nice score. I strongly recommend allowing for at least 4 hours to take in the entire experience, as three hours for our visit was not near enough to experience all that the museum offers. There are some nice surprise exhibits that give you a full on atomic experience, but I won't elaborate so as not to spoil the adventure! \n\nThey give you a special badge for the area 51 exhibit, which makes a nice keepsake, however, I found the area 51 exhibit to be amateurish and disappointing. \n\nThe rest of the museum was great, so therefore,  I highly recommend a visit to this very unique museum, you will not be disappointed.
