Passkey (the online events reservation service used by Fairmont) is a bit of a mess. The room availability at Passkey for FurCon seems to have been entered by drug-addled... I don't know. It doesn't match what the hotel reservations desk says is available. It's also overwhelmed by the load...

If you want a room for FC2010, you're better off calling the reservations desk and doing it over the phone. The numbers are (408) 998-1900 and (866) 540-4493. The event code is FURCON.
