Not sure if you have already taken care of this, but just saw this post. Check back all the time, especially if you are flexible in your dates. From what I have found, new inventory is added all the time, but I find it happens more often on Fridays and Saturdays. I have seen all of the DVC resorts in there at one point or another. I'm going on an RCI exchange to BWV in three weeks. Inventory changes all the time. May want to see what your change policy is with RCI, maybe you could book something, and if something else comes up, change it to the new one?
