Dash Point (although currently closed for some maintenance) is a pretty awesome place. Its not explodes with things to do, but I've camped there several times and enjoyed my stay though sometimes the showers beg for work. Not too loud, typically not too crowded, good space between sites. I've yet to actually get parked in one of the RV hookup sites, but i've walked by em a few times and they look pretty nice.
Also theres a couple nice trails to walk on to get down to the beach. My fiance really had a great time wandering the trails and the beach isn't too far away.
Heres a link to the reservation/Map page for it:
