We took our nephew on a whim since we were going to the mall anyway. He's almost three, and thought he'd enjoy the place.
My wife bought the tickets on her phone about a half hour before we got there. The tickets were for 4:30 pm but once we arrived they waved us on in, about 45 minutes early.
The trip through the aquarium was interesting, and our nephew really enjoyed seeing all the different sea creatures.
I thought it was great that you can make more than one trip through the exhibit, which we did.
It's not cheap, but we did enjoy the trip and my nephew has talked about it for a week now. As long as he enjoyed it, if say it was worth it.
