Came on Museum Day so it was free and likely more crowded than usual. Normal admission still cheaper than Phx Children's Museum (although they currently have a Groupon deal FYI). Being our first time we did not know socks are required for entrance into Artville (half of the museum) but I would have been prepared had I checked their website prior to visit. The museum is smart and sells socks at the gift shop. Luckily it's only $1-2. Despite the crowd, our 1 year-old still enjoyed herself thoroughly. The Artville side is for infants and up (saw 6 year olds in there too) and is full of fun. They have different little connected theme rooms - play kitchen and dining, building, vet, theater, train, infant area, etc. There was only one inflatable bouncy horse which all the kids wanted including my kid so it would be nice if they had multiple. The other side of the museum is for older kids and has hands-on craft and interactive learning activities. There was also an art gallery but it was closed that day. Of course there were good accommodations for kids like changing tables, nursing room, and large snack area with vending machines and tables. Overall fun for the kiddo. Have yet to visit Phx Children's Museum so can't compare.
