Agree about the San Francisco RV Resort. We stayed there two weeks this past August and used the BART frequently. We drove to the station, never had a problem with parking. We even went to an A's baseball game on free parking night! Many days we elected to drive our toad instead of taking the BART in depending upon where we were visiting. Good place and reasonable considering where you are. Parking downtown is available but very expensive ... to the tune of $3.00 for 20 minutes with a max out of $45.00! You can get some parking paid for via validation in Ghiardelli Square, Pier 39, and Fisherman's Wharf.
