We have a Sept. cruise and have booked a SFO hotel parking, then to BART from SFO to downtown and walk to terminal. With 2 suitcases that are carry on size it works well as we have done this before, any big luggage and its not easy. We also have parked at a BART station long term, it was good then, but crime has been a BART issue more in the past few years so use care where you park and your location.
