Here's one thing to learn:

Keep the concierge lounge open on the weekends! I am at the SFO Airport Marriott now, and this is the first hotel I've been to where they keep the lounge open on the weekends. Got me some donuts, drinks and other snacks to tide me over till an early big dinner. Combined with everyone being so friendly here in SFO, so far I'm really enamored with the hotel.
