Rebecca,
In Georgia there are tons of good options depending on how far north you are traveling.
Just to name a few:
Savannah, GA (Tybee Island, also Richmond Hill, GA)
St. Simons Island, GA (also Darien, GA)
Jekyll Island, GA
St. Marys, GA
Providence Canyon in Lumpkin, GA. (not sure about this time of year with wet weather)
Whistle Stop Cafe in Juliette, GA. (from the movie Fried Green Tomatoes, neighbors went & said food was fantastic)
Helen, GA (Alpine Village)
Athens, GA will be more picturesque and interesting than Augusta.
Have fun!
