I would suggest that you make your ressies as soon as you are allowed at your home resort. (You stated in another post that you just bought SSR.) If you are wanting to stay somewhere other than SSR, you can try to make ressies where you want to stay at the 7 month window. If you are successful, you can cancel SSR. You can also waitlist at the 7 month window, if there is no availability. But if nothing becomes available at least you still have your ressies at SSR. I would think that you might have a chance at booking OKW, maybe BWV and BCV, but VWL will be hard to get.
