I just looked at availability at all the studios from 12/1 to 12/6. The only resorts with all nights open in any category are SSR, PKW, Poly (Lake) and Kidani (SAV). But the key thing here is for all those booked resorts, it is not just 12/6 that is booked. In every category that has 12/6 booked, either 12/5 or 12/4 are also booked and in most categories, there is almost no availability from 12/1 through 12/6. This is not just walking. This is high demand. With walking alone and no high demand, you see the previous days come available and stay available. When you do not see availability at 10 months and 25-29 days, you might have walking, but you also have high demand overall and eliminating walking will not eliminate the issue of members not getting the rooms they desire.
DVC members love to stretch their points. The time between Thanksgiving and Christmas is already a popular and the points needed are lower than the holidays, so starting on 12/1 all the rooms are booked. I was not watching as we led up to 12/1, but if you had daily availability being missing at exactly 12 months leading up to 12/1, then members were walking to this week. Also, as of right not, only AKV club and BLT TPV are booked for 12/7, if this was walking, many more rooms would already be booked for tomorrow. IIFRC, they did actually bump up the points needed for early December in the last rebalance. They may do it again next time.
