As was mentioned earlier, there's probably some convention on at that time. Comdex starts on Nov. 18 and will (pratically) sell out the entire city, so prices are sky high. At the right time prices are good. I was at the Mirage last week for $89/night. Both Caesar's and MGM were a couple of dollars cheaper. I also recommend that you check not only the hotel's web site but also some of the airlines' sites. I've used Northwest Vacations a few times in the past and their prices have been pretty good.
