Someone wants the John Muir Room one week from now, making a Muir room reservation is different from normal reservations because you have to do this:
What is Check the availability both of the John Muir room and the East Ballroom (They're connected).
Because the Ballroom needs to be booked 3 weeks in advance, you MAY book the muir room, but ONLY when it is within 3 weeks (because then it is unlikely that someone could reserve the ballroom).
