Flying in and out of SF in Sept. We plan to spend a few days touring SF then a road trip via Hwy 101. We aren't going into LA but will turn around since flying out of SF. I know nothing of this area but have vacationed Yosemite, Tahoe,etc. and only am interested in SF, Big Sur drive and wine country (anything in those areas) if time allows. We have 9 days, including two flight days, so 7 for touring. Thinking of getting rental car at the airport and starting road trip first, turning in car at the end (due to parking?) and tour SF,2-3 days before flying out. IS this advisable? Also, am not sure how long we may need on the coastal drive, advice anyone, but do want to spend nights along the way down or back up to have a relaxing trip. Plan to see Hearst Castle . Can anyone advise of towns to overnight along the coast and sites not to miss. Also in Wine country.
