This place holds a lot of magic. I haven't seen the Chihuly exhibit yet unfortunately, but I can speak to a decade of experience in traveling here from the west side with my mother. Hell, I even volunteered here as a cactus in the summer and entertained children who for some reason wanted to hug a cactus.
This place isn't just for kids, though. They have literally hundreds of plants and other things (many of which you won't see anywhere else in Arizona) like pet rocks, and succulents of so, so many types.
The real joy of this place is it's proximity to the Phoenix zoo, which causes lots and lots of indigenous animals to come and inhabit the area during the day and night time.
Did I mention they have nighttime flashlight tours? I haven't done one but it sounds like fun. The only way they could improve this place is to make it free.
