My husband and I are moving from San Diego to Washington..we will only be in SF fro one evening on Sunday the 24th. From the rest of the reviews we will skip the Wharf and probably spend our time at GG Park. We want to take the elevator and see the GG Bridge. I don't know the areas at all!! Should we stay in Union Square?? Can we take a cable car or tram to the park?? We are in our early 30's..love great food, fun dive bars (NO CLUBS), love old things..including buildings, antiques, cars ets.... can anyone help us??? We'd really appreciate your time and thoughts!!
