All of the major hotels will be blocked out and committed to the Olympic Committee and the Broadcasting Networks. It is the same as what happened on Salt Lake City, in 2002 for the Winter Olympics. All hotels were blocked out and reserved by SLOC and NBC.
It was impossible to get a hotel room this far out. As time for the 04 Olympics draws nearer, you will have a better chance, as at the last minute the Olympic Committee and Networks may turn back some of the rooms. I would keep trying as time goes by, and would also check on private housing. Good Luck
