Hi Wallace,
There's not many. I stayed at RVacation in Selma for 2 years, (long story...) The park is very nice and very clean. They have all the basic amenities, including wifi. They are more of an overnight/short-term park, located right off I-95. (
www.rvacation.us). Selma/Smithfield is about 25 miles Southeast of Raleigh, at I-95 and I-70.
Selma has quite a few antique shops, but won't offer too many days of vacation fun for your family.
If you decide to stop in, say hello to Tony and Erin for us.
