According to the site, early registration is $110 for all 4 days. Fan Club members get in Thursday for free (non-FC members will not be admitted Thursday).
If you order between now and Thursday November 2, you will get an email Thursday morning (10AM PST) with details about discount hotel accomodations. Hotels close to the convention center that might say they are already booked for the dates of the con, such as the Figueroa, will have rooms available for those who order their C4 tickets online.
If anybody does this, let us know what hotel reservations you were able to get. I'll do the same.
