Woot! First post in Rides and Room sharing this year! Muwhahaha!
There's a way to [ab]use a site that finds hotels near universities, and make it tell us where to find hotels near DefCon...
Search for Hotels Near The AP/AV around DefCon (Custom URL [ab]using collegehotelguide.com)
NOTICE: Avoid OnLine reservations from 3rd parties! Best advice: call the actual hotel's front desk for reservations once you find a hotel.
(Call hotels even if they are "Sold Out" -- say you're with DefCon to see if they are still "Sold Out.")
Thanks to renderman for the Lon/lat posted in this thread.
