Update from RobinZ via email:
"Location update: the courtyard is closed today because of an event tomorrow; the staff at the front desk suggested sitting in the Luce Center. It is on the third floor, F Street side, to the right if you are facing F Street or the left facing G Street.
(I got there by going in the G Street entrance - where we usually leave at the ends of the meetings - turning right, going up the stairs on the right side of the hallway immediately before the room at the end of the hall, and then continuing around to the right after leaving the stairs at the third floor. There is an elevator in the building, though, and the staff at the desk can direct you.)"
