Visited three eras: age 4-65. There's a lot to watch (it takes a lot of walking), and there's a lot of dinosaurs, as well as North American animals and other more exotic animals. We mostly went to the dinosaur area, but it was a bit shabby and there was litter. Many bad children climbed the partition and ran all over the exhibition area. Some of the electronic animations didn't work. Coffee is very common. We will go again this year. Nevertheless, I wish you all the best.
