How much time to see the Georgia Aquarium in Atlanta?

I'm traveling to Atlanta for business in a few weeks. I might be able to sneak away for a few hours to go check out the aquarium. How much time should I budget to be able to see the aquarium and enjoy the exhibits without having to rush through the place?

Thank you.

Take at least 2 - 3 hours in order to really enjoy it

First answer is right. 3 hours will give you time to really check everything out.

I would say 2-3 hours should be sufficient
