I agree lots to see in KY. I'm originally from KY and go back a couple times per year. Live in NJ now.
I stayed at Grandma's RV last year, and while it is in a good location for sight-seeing, I cannot recommend that park. The accommodations are VERY tight. No room to sit outside plus no/limited shade. The bigger issue is the attitude of the elderly owner (Grandpa?). He is very rude! His son was more accommodating and a little more friendly.
This year we will be trying the KOA that is a couple miles away from Grandma's. We drove through it last year. Seems nicer but is a little more expensive.
