I'm an RCI Weeks owner (passed down from my grand parents, it ends in 2021).. Ongoing searches for Disney properties have been tough.
The only Disney resort I've ever seen available has been Disney's Saratoga Springs(DV06) 1 Bedroom. Just recently I saw for April 2016 (27 points one week, and 30points another).
My searches have never shown anything unless I had enough "trading power points" banked. Even ongoing searches.
I'd love to get something like Bay Lake Towers (DV09) or The Villa's at Disney's Grand Floridian (DV12), but no one at RCI can ever tell me how many points are needed for ANY Disney resort, nor can they give me any tips or suggestions other than to do an ongoing search and hope!! They also suggest doing the search even if you don't have enough points, and bank/combine when you earn more, since once you are in the queue, you keep your place in line when something comes available. (not sure that I buy this, but several of their people told me this).
Of course there are plenty of off-site resorts for exchange to stay in that are bigger room with full kitchen and washer/dryer, and with way lower point values. Some are even very nice. But you don't get the Disney perks of Magic Express, 60 day fastpass, transportation, etc.
