We will be flying PHL to SFO and want to stay 2 nights in the beautiful CA wine regions on a Thurs.&Fri. nights Sept. 12,13. Should we spend one night in Sonoma and one night in Napa or stay both nights in the same location somewhere in between? I also want to see Muir Woods and the Point Reyes National Seashore on the way up or back. Already discovered that a last minute decision to travel causes angst as many of the B&B's are booked and we may have to resort to a chain hotel. We love CA wines but spending a lot of time in tasting rooms is not our thing so looking for a few special off the beaten path places. Thanks for your help!
