Hi D.,
It depends on what you like to do. One relaxing place if you like camping/woods is Skyline Drive. They have cabins that you can rent or camp in a tent.
If you like the beach, there is a campground in Myrtle Beach down near Surfside Beach, (on the south side of Myrtle) that isn't too expensive. THere is also alot of condos that aren't too expensive.
If you want something closer to home, Williamsburg is quaint. Not too expensive, and if you wanted to you could go to the beach that's an hour away for the day.
Best of luck.
M.
