I see plenty of cars at the ramps overnight but I wouldn't push my luck too far past midnight at any of the other parking areas. I've been asked to leave the pier parking (baby beach) lot after 1am by a security guy once before.

For launching at the south (Doheny) beach area you can beach launch south of Thor's Hammer where paddleboards are allowed, although at evenings I don't think many would mind you launching near the jetty. Parking past midnight there is a problem though. I've never been but suppose one could pay to get in the Doheny park campground area for overnight parking, but at that point might as well pay for the launch ramp.
