Don't listen to the negative reviews. Most, of which, are just complaining how over priced it is. That's a lack of common sense. They have a big facility and lots of big tanks with big animals. It's not sea world but for an aquarium in Phoenix it's pretty nice. Plus when you raise minimum wage to $10/hour and you need lots of employees, veterinarians, maintenance repairs etc. they couldn't stay in business.
My family all loved the Life Carousel. Definitely recommend you go to the bathroom when you first get there. I know sounds strange, but just do it. The 3D show was pretty cool too. They're running a special after 4pm and we got $10 vouchers. That means our ticket prices were $15 after it's all said and done.
