Since this is a
DVC resort, it may be somewhat more likely than it would be for one of the PO resorts as long as there's availability for the room type, studio or 1+ bedroom(s).
Could be touchy, though, as fully booked as DVC resorts typically are.
Depends hugely upon which DVC resort. The smaller ones may not be able to at all; the larger might be able to do it. Being an owner rather than paying guest can have the advantage for such requests. DVC resorts endeavor to make Members happy if at all possible.
