I'll be in SF on business for several days in February and was thinking about staying for the weekend. My husband has never been there before so he might fly out to meet me. Can anyone help with some advice on planning?

We were thinking about using our Hilton points to pay for the hotel, but I'm not sure which property (or even which general area) to pick. Ideally we'd like to skip the rental car, and walk or take BART--we're on a tight budget--but is it feasible to see the major sights this way? Any suggested itineraries for such a short trip?

Also, I think the Chinese New Year's parade is the weekend we were looking at (Feb 7th?). Would this be worth seeing or will it be a total mob scene?

Thanks!
