Availability even at the DVC resorts can be challenging. You differently need the 11 month advantage. We own at BCV and we have not yet been able to get the type of room we want, when we want it. I have been told that we travel at the wrong time of year and that we expect too much. I guess for what it costs, we expected better availability. DVC MS has too many problems in my opinion. Posting problems, website problems, reservation mistakes etc. By now you would think that they would have the bugs worked out. My best advice is to buy a small resale contract at the resort you like the most. Take DVC out for a test drive. If it doesn't work out, sell it and move on. It's not a life long commitment.
