I took my boy here when we visited Las Vegas. I wasn't SUPER impressed myself, but he had a blast. Especially in the room with all of the creatures. One of the staff pulled the lizard and the snake out and walked around to let the kids touch them. I got to hold the lizard. It was pretty cool, but I stayed clear of the snake!! I think my favorite part was the underwater area. They had a large pool with some little sharks in it.
The staff was really friendly. The lady upfront reminds me of my granny lol. There's a little shop filled with pointless nicknacks and toys, but of course I had to get my boy something that broke a day later. I think my least favorite area and I think I can speak for my son, was the Egyptian exhibit. It was the least interactive area in the whole museum.
