I used to go down about once a month surfing, etc. when I lived in San Diego. It's been > 25 years for me now and my girlfriend has never been down so it'll be pretty new to both of us. Many places that were not accessible then, are now by road and many places now, you also need reservations! I guess they call that progress (but that's why I left SD).
The best places still don't need reservations..
