We stayed at sanfrancisco Rv resort on the coast in Pacifica. Big storm when we were there so didn't enjoy it much Rv rocked with scary wind and sea spray turned my black truck white with salt spray. . I think next time we would try the Koa in Petaluma or stay near San Jose and drive in. Sanfrancisco can be very cold windy and foggy so be prepared. It is a micro climate and very different than areas like Silicon Valley or wine country in napa. We took a tour in a van with a small company called California land safari and it was very good. All the highlights except Alcatraz which we weren't interested in. Very informative guide. We never would have come near seeing as much on our own. 2nd day we took the Bart back to Chinatown to shop. It is a very historic city and the background stories are fascinating and a good guide will tell those stories to make it come alive. Enjoy your trip.
