H.A.
Depending on how far you're willing to travel and how long you'll be gone . . . last year we met my family (who live in Alabama) at the Genral Butler State Resort Park in Carrolton, KY. They have "cottages" there with full kitchens, A/C, etc. It was close enough to Lexington to go to the Horse Park and see things there and also close enough to Cincinatti for a day trip to the Cincinatti zoo (rated one of the bed kids' zoos). We were only there for a few days, but it was very relaxing. There's also a lodge with a pool as well as golfing, mini golf, and camping at the State Park.
