In San Diego, Campland on the Bay is one of our favorites, the are located on Mission Bay accross from Seaworld, they have their own beach and marina in the bay too. They are only a couple of miles away from the Boardwalk at Mission Beach. They're private so they cost a bit more, but last time I was there they were a decent, clean, gated and have 24 hr security.
