While visiting Cincinnati we decided to travel past state lines and go into Kentucky to visit the Newport Aquarium. Actually, I believe the Cincinnati airport is actually in Kentucky (anyone correct me if I'm wrong). The Newport Aquarium was absolutely great -- there were a ton of great exhibits, I can't even remember them all right now. There is a cool bridge passage, penguin exhibit, sharks, etc. There are tanks where you are actually walking under where the fish swim. There is a huge crocodile exhibit as well. Basically, it's an incredible aquarium and great value. I believe you can even save a few bucks by ordering tickets online.
