You go outside of baggage claim and get on a bus. That bus then takes you to the train station. You get on the correct train (Daly City for SF?). You get off (we'll be getting off at Powell St.).
Do I have this right so far?
My big question that I can't seem to find, is if there are any STAIRS involved with this process? Or is it all one level or elevators/escalators? Barring the fact that at escalator might be broken, etc., for normal times will there be any stairs we'll have to lug our suitcases up or down?
