Did you try searching weeks using your the same points? I don't think you can pull any points resort using weeks search. You have to also own a week that trades on the weeks side. You will have a different login name and login to RCI weeks.
I noticed in the RCI directory, that the Disney resorts had two different codes, one for Points and one for weeks (i.e. DV01 & RD01). In theory, doing a weeks search from a points sign in should be able to see the DVC weeks, but I'm sure RCI blocks this function. For example, for a 1 BR in May was 56,500 points (even higher in June & July). If this same resort was obtained via the weeks search link, then the points required would be 43,000 (based on the RCI grid).
I can see various DVCs with a Points search, but those same resorts and weeks do not show up using the weeks search.
Also, if I requested a search on a single Resort ID, such as DV01, I saw availabilities, but if I did a Region search, I did not see availabilities at DV01, but when I did a region search a second time, DV01 showed up and others that were previously there were now gone. Does RCI limit the number of resorts displayed when doing a region search OR is inventory really changing that fast?
All that being said, unless a family wants the Disney experience, you can get a 2 BR at other GC resorts (Summer Bay, Orange Lake) for around the same number of points (or less) than a 1 BR DVC.
