We stayed at Nashville Country RV Park one time a couple years ago for the Passport America 1/2 price but have been staying at
Two Rivers Campground the past 2 years. The PPA savings was lost by traveling back and forth everyday and I-65 can become a parking lot in a hurry.
Two Rivers is a Good Sam park and is close to the Opry and Bass Pro shops and a huge shopping mall. They are next door to a Montana dealer and 2 doors away from Camping World. Every night 2 Rivers has live entertainment. They offer shuttle service to and from the Opry.
If you do decide to stay at Two Rivers be sure to ask for a site away from Grayline tours bus barn. Those busses are in and out all night.
For the past 2 years Nashville has been one of our stops after leaving the MOC rallys in Goshen and it will be again this fall.
