Do this so you know which sites or sites to reserve because if you start looking for a spot at 8 am, you’ll be late. If possible, have multiple people on the computer ready to click “reserve.” at 1 second past 8. If you need multiple sites, have multiple people so you don’t waste time clicking two things.
I have tried, on and off, to reserve one of the Crystal Beach Cottages. They always sell out in about 30 seconds. But, that is the extreme. You can get a beachfront Doheny location if you do it right.
Non beach-front sites are usually available longer. I have booked these an hour later.
Beachfront at San Elijo are way above the water. Same for Capistrano. Beachfront at Doheny is on the sand.
