You didn't mention your time frame. One of our favorite trips we started out the last two weeks in September at Acadia NP (camp grounds close the first week or two in October). We then headed south following the fall colors and visited many of the Civil War and Revelotionary War sites. We stayed anywhere from one to two weeks at each site.
Seeing some of the battlefields in full color was amazing as well as thought provoking.
