We stayed at the campground that is right next to Graceland for several nights last April. It was a nice, quiet campground, and you can walk to Graceland. Neither my wife or I are big Elvis fans, but we really enjoyed our visit to Graceland. Gave us a new image of Elvis. We felt since we were passing through anyway, and we are retired, why not. We got picked up in a pink Cadillac and driven to a local pulled pork restaurant, and returned right to our camper...no charge. And the pork was great!
There are several nice COE campgrounds around the Lakes. I would recommend one of those over the many private CG's in the area, althought there are some very nice ones they can get a little pricy. Hillmans Ferry is one COE campground in particular I can recommend---nice park, priced right, and lots of sites to chose from.
