Possible, depending on whether you've waitlisted a studio or a 1-bedroom. But we're already inside the 7-month window so I would have expected any movement by OKW owners switching to another resort to have occurred already. People cancel reservations all of the time, so anything is possible. I'd say that your chances of success would be better with 1- or 2-night WLs than a 4-night WL. And stalking the member website for the days you want wouldn't hurt, either.
