Took grandkids 5 and 2 on a Wednesday afternoon so not at all crowded. Got tickets through Viatour so a bit of a discount which helps. Very clean, smiling courteous young staff, neat array of sea life. Liked it a lot.
Disappointed in this tour. It was not what I expected. I was thinking more higher End Sea World type aquarium. It seemed more like Sesame Street. It seemed to cater more for the preschool level. It was very obviously geared more for small children, or adults taking their small kids to see aquatic life for the first time.
Adults and children enjoyed the Sea Life aquarium. Nice way to spend a few hours in Phoenix. Viator made ticketing easy and affordable.
