we live about an hour from Memphis and 4 hours from Nashville. i got to agree with everybody else, Nashville. if that's what you decide, look into Montgomery Bell State Park. beautiful small park about 20 minutes from Nashville, sites have full hook-up and right on a creek bank. lots of other state parks around that are nice but that's the closest. have fun.
If you are into history, the Nashville area has quite a few historic battlefields. Fort Donelson National Battlefield is 1 mile west of Dover, northwest of Nashville. This would make a good day trip and a great place to have a picnic lunch.
As mentioned above, be sure to see the Parthenon. It was built for Tennessee's 1897 Centennial Exposition.
We typically stay at Cedars of Lebanon State Park. It is about 30 miles from Nashville. The campsites are paved and well shaded. It is 6 miles from the interstate and is very quiet. Of course there are other campgrounds closer into town.
You may want to check on what events are occuring at the time you will be in the area. Fan Fair draws a lot of people and many campgrounds fill up.
