My wife and I plan to undertake a circular road-trip next year, starting in Washington DC where we plan to stay 4 nights. We are experienced US road-trippers and have visited Washington and some parts of the South East before. However, we have yet to drive through Shenandoah and the Blue Ridge Mountains or visit the National Parks in that area. Savannah and Charleston are also on our list of must-do's (where we would probably want to stay 3 nights in each). We'd very much appreciate advice from anyone who knows the area well and who could offer any suggestions to assist us in planning a 4-5 week itinerary.
