You might find a confirmed reservation for your time....you may not.
DVC reservations are generally made seven to eleven months out from travel....with popular resorts getting booked up before the seven month window. So you are looking for someone who booked a reservation that they can't use, or booked one as a "spec rental" and hasn't rented it yet. And you are competing with everyone who is also looking for that reservation. Your choices this close to travel are likely to be slim or none - but better because you have at least some flexibility in dates.
Make a cancellable hotel reservation so you have somewhere to stay if you never find anything.
