Rex is right about the long walk. We stayed in the Two Rivers campground close to the KOA and it isn't convenient to walk to the Opryland hotel or mall. You might check with the KOA as they may be able to call a shuttle for you to go where you want when you want. I have forgotten what we paid to get to the Grand Ole Opry and the mall earlier this year but it was very little, just a few dollars. I rather think the KOA will offer the same service as it was offered by the Opryland hotel folks and not the campground. We liked Two Rivers very much. Spaces are a bit tight but manageable, and they have live music a couple of times a week. Enjoy Nashville!
