The 25% Member discount may not be available right at 11 months, but could still be applied later if/when available (this would occur automatically, you do not need to call back to check). If a cash night is available for the dates you want, I'd reserve it and hope that it will become a discounted night. The first priority for MS is to make
DVC reservations using DVC points. For some dates, there may never be cash availability (although that is unlikely) but no discounted rate since they will need to see if the villa will be needed for DVC point reservation - either from reservations made or from past history for that resort/villa type/date. In most cases, it would be weekend nights that are most likely to be available with the cash discount, but week nights can also be discounted. Good luck!
