The Southern Charms Fan Box

So in a few weeks I will be going on vacation and I am looking for ideas. We are going to Myrtle Beach for a few days but then we have about 4 days with no plans, just making it back to PA eventually. I really just want to ride up the coast and check out new places. I haven't been anywhere between Virginia Beach and Myrtle Beach. Any suggestions on good beaches to visit? Are there any interesting areas with a little privacy to shoot an update? I am really excited to see what we can get into and to share it with all of you. Any ideas are appreciated!
