It won't be hard to miss the Banks by the stadiums. Vine St. in OTR has some excellent places to eat and drink day and night. Go to Arnolds, the oldest bar in Cincinnati. You might be able to catch a Bengals preseason game? Kings Island is pretty fun if you want to go on a Tuesday morning or something you'll likely not have to wait for any rides. I haven't been in forever, but understand they've got some great rides. Mt. Adams is a unique area to view the whole downtown area from high up, and they've got the art museum and Eden Park which are both great. Union Terminal isn't far from downtown and the building itself is really cool.
