KY Horse Park is a good choice to stay when traveling to the Arc Encounter, it's only a 40 minute drive. Also, you could spend an entire day at the Horse Park and not see it all. Lexington has lots to see and do and the horse farms that ring the city are a treat to see. Pleasant Hill, a restored Shaker Village, is not far away. The Creation Museum is about a 90 min drive off I-275 that circles around Cincinnati. There is an Indian Springs CG in North Bend Ohio that is about 15 minutes North that can be seen on the West side of the Interstate but I don't know anything about it.
