I think you mean using your
DVC points to stay at non-DVC WDW resorts? They do vary widely based on type of room, resort, day of week (Fri-Sa nights are more) and season. There is also no guarantee that the points will stay the same, they can and do increase year to year. (This doesn't happen at DVC. At DVC, if something goes up, something else has to come down - the total does not increase.)
That said. Using points to stay at non-DVC resorts is okay for variety but "costs" much more than staying at DVC for accomodations that are not as deluxe. But, it does give us the option not to "miss out" and to use our pre-paid points.
If you have a particular resort in mind I can be more specific but to give you a general idea --
Moderate resorts range from 14-40 points per night.
Deluxe Resorts (non-Concierge) range from 26-119 points per night. Concierge ranges from 85-158 points per night.
Ft. Wilderness Cabins run from 25-67 points per night.
