Savannah....food is incredible. Go to "Huey's". (Menu is online.) It faces the river. I eat there, only, every night... when I've been. The city is not crowded like Hilton Head and Charleston.
For seclusion, a place I've not been, but have heard a lot about is Cumberland Island, Georgia.
Saint Simon Island, Georgia is really beautiful.
A small but quaint place that I love is Beaufort, South Carolina.
I love Beaufort, North Carolina even better. Use to keep our boat at the yacht harbor there. Very, very old seafaring community. Lots of history.
These are resting spots, fun spots for relaxing. They're not dog, horse and Nascar track destinations. Busy as all get out in the summer, but not the winter. Ate on the waterfront at Beaufort, NC Friday after Thanksgiving. The weather was sunny, warm and beautiful.

Do not bother with Myrtle Beach. Every snowbird that no longer chooses Florida has chosen Myrtle. The traffic is a nightmare!! And they CANNOT drive.
