We live in Dayton as well and just spent the weekend at Kentucky Horse Park Campground in Lexington. It's only 2.5hrs, but it is a very nice campground with a large pool, a couple playgrounds, tennis courts, basketball courts, bike trails into Lexington, and of course the Horse Park itself which is really cool. My daughter got to ride a pony and if she was older they offer trail rides as well as numerous other shows and attractions. We spent all day Saturday there.
