You might also look at County Campgrounds by County. We have stayed at quite a few just fine spots, some are so inexpensive and still have electric plug ins.
As with every campsite, people move out all days, some have three days to get home, so leave Friday morning, others are there for the whole weekend. It's always good to arrive very early when it's busy, and sit for a day or two if you get a decent spot and it's busy.
Harbor Vista is a good spot, only a couple sites have views, but we have managed to get those sites in February.. nice.
