SC places to stay
Myrtle Beach--State Park is ocean front, campsites are wooded. Lovely. Many other CGs in area.
As for weather, usually in upper 40s lower 50s daytime, can be freezing at night, but usually upper 30s this time of year.
Locals know if you don't like the weather today, wait a couple days and it'll be different. Ocean temps keep air temps moderated.
Charleston can be, on average, 5-7 degrees warmer Jan and Feb.
Good luck. Safe travels.
