Took my daughter here on a hot summer day. This place is huge and my daughter had so much fun. 3 floors of interactive exhibits and a very tall play area in the middle. My daughter loved the water exhibit and the fantasy area. Her favorite part was probably all the slides in the middle. There's also an art station on the 3rd floor that was fun. Overall, I would definitely recommend this place. There isn't much to do indoors for kids in Vegas and I know that I will be back with my daughter over summer.
