For the time you want, third week of October, the difference between using the 11 month reservation window (for which you need an owner of the particular resort) and booking 7 months out (when
DVC members can book DVC resorts other than their own) is like night and day. It is a high DVC demand time. For third week of October 2016, BLT standard view booked most nights full very quickly at 11 months out, theme park view took about a month to mostly fill thereafter, but lake view was still open at 9 months out, but by 7 months out all sized lake view rooms were already full for 4 to 5 nights of that third week in October. At AKV, value and club level rooms filled extremely quickly once the 11 month window opened. Most everything else at AKV was still open at 9 months out, but by 7 months out, the only things open for the full week were standard view 1BRs at Jambo and Kidani and savanna view 1BRs and dedicated 2BRs at Kidani. Everything else was missing multiple nights and the standard 2BRs were already full for five nights (at Jambo), and four nights (Kidani, both lock-off and dedicated 2BRs) by 7 months out from the beginning of that week.
Thus, particularly for the time you want, and any time in the last quarter of the year, you should try to get someone who owns at AKV or owns at BLT to do the reservation using the 11 month reservation window.
