We stay in the Econolodge in Lebanan, TN. It is cheap, clean and actually not bad. There are plenty of restaurants in the area and it is within about a 15-20 minute drive from a ramp up by the steamplant and probably 20 minutes from the ramp at Flippers. I used to stay at the Comfort Inn in Gallatin, but it is now close to $100/night. The Econolodge in Lebanon is under $50 in the winter and around $50-$60/night in season. Good luck!
