A poster above asked "why would anyone want to stop in SF?"
Well, it's a great city. As long as one avoids Hunter's Point, it has been safe as any major city. Still some interesting and free things to do. A launching area for a trip to the Napa Valley wineries, if one is so inclined. Some great sailing, and usable venues. Besides, if the OP's good lady chooses to fly in, lots of flights.
Do agree some people like Moss Landing,
Santa Cruz (but hasn't it silted up?) and Monterey, with its
history and aquarium.
