Just a correction... it is the Stanford
Court and not Park. Don't want you looking for a hotel you cannot find.
BTW, the Stanford Court (do a search in Marriott, you'll find a few threads,) is my favorite SF hotel. It is on Nob Hill, but not the top, so you save a little "up hill" walking. Sits right on the corner of California and Powell... where ALL of the cable cars cross. You can get anywhere easily from this hotel because of it's cable car location. (You can also buy multi-day passes for all public transportation at the newstand downstairs which really cut the cost of getting around.)
I could go on and on about the hotel, but won't. Stay there, and you'll be very happy.
