First off, this is really not a fair review of this place. I don't have kids nor do I like kids but, regardless of that, they had a Spring Training exhibit that was geared more towards adults and I had to go, so that's why I'm writing this review.
It always bugs me when an address is not correct. The address for this place is on Robson but the only thing on that side of the street is a big wall. There is no entrance there. The entrance to this place is on Pepper and it really should be addressed accordingly. Besides that, this building is not really much to look at. Compared to the Phx Children's Museum which is AMAZING, this wasn't much.
The baseball exhibit was decent but lacking. It wasn't laid out in any particular order and it was really missing some important pieces of history. There was almost no mention of spring training in Casa Grande, Tucson, or Yuma. There were very few photographs which is another shame. There is a ton of text to read (which is why I think this is geared towards adults) and some random memorabilia that doesn't have anything to do with the Cactus League.
It was worth the price of admission but I'm not going to be telling anyone else to go see it any time soon. Unless you are a huge baseball fan, it is pretty lame. We have more memorabilia in our house than they had there.
