My husband and I are planning to drive in early July from San Antonio, TX to Williamsburg, VA. We've already mapped out a visit to Jekyll Island, Savannah, and Charleston. We leave Charleston on July 5 and have reservations in Williamsburg on July 8. Any suggestions on route, things to see, etc. for this part of our journey? We haven't been in the area before and probably won't visit again by car. Any suggestions are appreciated!
