I come from West Virginia, and I like to stop at Walterboro, SC. Others on these boards also like Walterboro. I get there before dark, and it is only 6 hours' drive the next day to WDW. You could choose to drive another hour down the road to Savannah, GA, but prices are higher and you may lose your daylight. I have stayed at the HI Express, Ramada and Hampton. I was going to try Microtel next. I like that it is across the street from Cracker Barrel (if you like their food). Look for specials before making your decision. I think all of the motels have free breakfast of some sort.
