The consummate planners that most Disney fanatics are (since our trips are normally expensive and extensive), it is hard to grasp the fact that many hotels do not post rates more than six months out. The most you will find is normally 12 months. I know it can be frustrating, but just hang in there and call on day 179 before departure. If you can get rates for December 2005, they should be fairly close to what you should expect in February.
Good luck!
