I know I'm a bit late, but I had a wonderful time. San Francisco was one of the best trips I've been to here in the USA. I think its a stop of a lifetime, and I recommend you go there too! Make sure to go to:
-The Golden Gate Bridge (Some people get lucky enought and walk it)
-Coit Tower on Telegraph Hill (maybe you'll find some parrots)
-Fisherman's Warf and Pier 39 (see my video below)
-Sonoma Valley (a beautiful place, and a great stop if you like wine!)
Here's a short video I took while at Pier 39 of the Sea Lions. Enjoy!
