Booked a room at the San Francisco Marriott (Moscone Center) for Thursday & Friday nights at the concierge level rate. Details for the room show the lounge is open 7 days a week (and still does). Got to the hotel, checked in, and was given a sheet with info about the lounge. When I got to my room and read it, it says the lounge is closed from 12N on Friday to 4 p.m. on Sunday. Went back to the front desk and asked that the rate for the 2nd night be reduced to the lowest for which I qualified (and thankfully which I had happened to print out before leaving home). After some phone calls, they did reduce the rate for the night the lounge was closed, but I had to initiate the process.
