Went here two days while in Phoenix. We are members of a reciprocal museum so admission was free. My main companion was my toddler in need of an air conditioned play area away from the August heat. Most of the venue is more for slightly older children, but my kiddo enjoyed the concrete water play area and the home builder exhibits. I wish there was seating in the water play area - only a concrete wall to lean against. Some tyrannical older children who are allowed to roam wild without parent supervision can ruin areas or a day here.
