We've driven to FL twice, which is quite a bit longer than GA (as the states get bigger when one leaves the NorthEast). Guessing you mean Atlanta.
The trip can actually be done in one very long day if you hit Balt-DC-Richmond just right, but you sensibly want to stop. So it's not two full days of driving unless you take a long time or a lot of breaks. Figure 4- 6 hours of driving one day and 6 - 8 hours a 2nd day.
We stopped in Richmond a couple of times, which is good if you leave in pm from NJ and hit Baltimore after 5:30'ish and go Washington-Richmond in the evening (NOT on a Friday).
Durham - High Point is a nice area, with things to see and places to shop, and a little farther along.
Underground Atlanta . . . Fox Theatre . . ..Civil War history (Kennesaw!) anyone?
