All I ever read is buy where you want to stay. I also read that most people have no problem staying somewhere else at the 7 month window. Also many predictions how it is going to get harder to stay as SSR fills up. I don't think that is an absolute rule yet if you can be flexible with your weeks and room selections. In my case I don't care where I stay as long as it is on the property, so I bought at OKW. The lower fees and the fact that I can be flexible with my vacation make it a good choice for me. I really think it is not a hard and fast rule to tell new buyers as there are many of us who are just happy to stay on property. I will sell my points if the system becomes rigid and I will have to always book at 11 months out. I say buy what you can afford! Any property you buy at DVC is a good investment in your vacations.
