I would go to L.A. first and that would be to see the Nixon and Reagan libraries and museums, the Getty Museum, the Queen Mary, and a few other places in that locale. Not feeling a big urge to go to San Fran in any case.
Visited SF back in the 80s.......a cool and unique city but observing many of the people, even back then I could see where it was going.
Don’t forget the Huntington Library and Arcadia Arboretum — two wonderful places I used to take my dates when I was broke.
I stayed at the Queen Mary. My husband and I went exploring. I know we explored a few lower machine depths. Kind of like the Poseidon Adventure.
