This aquarium was impressive.
The displays bring you on a winding path through the world's waters. I was pleased to learn more about the Great Lakes, for instance, and to find that the display (from the tank design to the educational materials) made them incredibly interesting (normally I would head for the sharks and jelly fish, for instance).
There was an easily, naturally followed path with plenty of options in terms of creatures and information to engage with.
The children's play area was a real hit with my little niece. She loved crawling into the tank tube and touching the rays especially (okay, maybe the rays were my favourite).
It's expensive, but not more than any other attraction be it a museum, theme park or the movies. You can also spend a whole day with the family and get plenty of hours of fun, learning and quality time together.
