The only negative to this museum is that there is so much to see! We stayed a few hours and could have spent even more time here had we the time to spare. My 16yo loved the historical aspect of the Buffalo Bill area. My 12yo loved the passport in the natural history area. The price was a little hefty and it was actually cheaper for our family of 5 to buy the yearly pass (which really makes no sense, as we live 3 states away... but did it anyways to save the money). All in all a great visit and a great museum.
