Yea for having an aquarium in Arizona! This was really neat and something different to do in our landlocked state.
I loved racing my niece around to look at different tanks with her (and beat her to the next one). The main tank was closed (lame) for preparation of sea turtles (wicked), but there were plenty of other things to do and see around this place. I loved the exhibit where you could hold different sea creatures, mainly starfish and hermit crabs - oh and so did my four year old niece. The best part of the aquarium is that they stamp your hand for readmission which is awesome because then you can go out and explore mall. We went through once, left, had lunch at the Rainforest Cafe, and came back again a second time before we finally departed Arizona Mills.
Would have been 5 stars but the ocean tan/main tank was closed. But, whether you are four, (or possibly) 27, or 64 years old, this place will keep you occupied and make you temporarily forget that you live in the Sonoran Desert.
