september, going to San Francisco (2 nights) and then Napa Valley (3 nights). Never been to either. Recommendos please. No GMAFB boring crap (alcatraz, curvy street, ghiradelli, etc) please.
3 nights is a lot of time to spend in napa imo
Well maybe 3 nights in SF and 2 nights in Napa. idc.
Agree on 3 nights in Napa being too long. I feel like that can be a day trip but I suppose if you're really into the food scene there you could spend more time. There are plenty of day tours that can pick you up in SF and take you to a few wineries and get you the general idea of the place. Could save you from renting a car. IMO you've seen one winery you've seen them all.
you should do the cable car on the Powell-Hyde line even though it's touristy. It's worth walking around Chinatown and along the Embarcadero too.
Museum nights are good on Thursday nights (or so I've heard).
You're far enough out you could try to get a reservation at State Bird Provisions (just need to log in at midnight pacific 60 days out and hope for the best)
Could recommend specific events depending on specific nights you're in town and what you're interested in when you get closer.
