sonyxperiageek:eracode: One time we were there we did a road-trip of a week or so - an anti-clockwise circuit - south through San Jose > Yosemite > circumnavigated Lake Tahoe > Sacramento > over to the Napa Valley then back to SF. Calistoga and St Helena in the Napa are really lovely places.
We just totally winged-it for accommodation each day - using booking.com on the fly from the car - but that may not work so well during peak vacation time.
Where did you hire your car from?
Avis - 333 O’Farrell St but we dropped it off at the airport on the way out. It costs a bit more to return the car to a different point but it made things easier/we didn’t have much other choice. I guess we could have dropped the car back where we got it and then caught BART out to the airport (which actually works OK) but not so easy if you’re lugging suitcases etc. Or caught a cab for $$$.
Actually BART to (and from) the airport does work exceptionally well - the trains go right into the terminal - get off the train, walk through sliding glass doors and you’re right at the check-in desks.
