It looks like the hotel has debugged the reservation problem - you can use the link below to reserve your room for MillenniumCon 10-13 November. Go to this link, adjust the dates and select the room type.
If you have any questions just shoot me a note. The hotel is filling up and will be SOLD OUT by the end of summer - so don't wait too long to book your room.
More information about the hotel can be found on the Hotel page.
