Best route and/or scenic route from Lufkin to Gatlinburg taking 2 overnight stays along the way before getting there and 2 overnight stays along the way returning to Lufkin. We are older and want it divided into thirds getting there and returning. We need to stop a lot for bathroom, gas, and food breaks. Any and all suggestions for safe places to stay and moderately priced dining will be greatly appreciated. Feel free to suggest any interesting places to stop and visit along the way that are not terribly time consuming.
