Assateague State park has some electric hookups. NP has no hookups but allows generators in 2 loops. Kiptopeke State Park is in Va about an hour south on the DelMar Pinninsula. They have full hooks and cable. In both cases it is a short walk to the beach. But anywhere at the shore you need to book months or a year in advance. Everyone wants the weekends. But if you book from Sunday to Thursday you can sometimes find a site especially in spring or fall. We love September at the shore. Fewer people and easier to book a site.
