overnight between Blairsville, Ga. & Biloxi, Ms.

We did stay at The Woods in Montgomery, AL. Close to Interstate and Truck stop across the street for refueling. From there we drove to Augusta, so from Blairsville, it should work.

Within easy walking distance to a few eating places if you don't want to cook.

Woods RV Park on I65 just after Montgomery may meet your needs. We have never stayed there but on Maps it looks fine for a overnighter.
