When are you going? If you go during the spring/summer, there is Kings Island, the Cincinnati Zoo, Coney Island, Cincinnati Reds games, the Beach Waterpark, Great Wolf Lodge...They also have the Newport Aquarium & Ride the Ducks (across the river in Northern Kentucky). There are plenty of things to do in the area. Southeast Indiana & Northern Kentucky are right there too so you are likely to find things for these areas if you google Cincinnati.
