Thanksgiving week is the fourth highest DVC demand week of the year at WDW (behind first two weeks of Dec and Christmas week). GVs for that period have a risk of filling within moments after 8 a.m. at 11-months out (winners are simply those whose computers communicate faster with DVC's computers right at 8 a.m. at 11-months out). Moreover, late Sep to marathon weekend in Jan is the high DVC demand "fall" season and those GVs may disappear right at 8 a.m. 11-months out for some of the other times during that period. If you are going to do a walk, you should consider starting in early Sep (unless you have an Oct use year, in which case you have to wait until Oct to start a walk to Thanksgiving).
And be aware as a new BWV owner that much has changed since when you were previously an DVC owner. BWV standard view studios (and 2BRs since all are lock-offs and thus a studio reservation means the room can no longer be reserved as a 2BR), now fill almost instantly at 8 a.m. 11-months out year round. Ten years ago they were often open long enough at 11-months out to easily make a reservation for many times during the mid-Jan to mid-Sep moderate demand season. In 2016, DVD decided to change the room capacity of the studios to five persons rather than four. The result is that standard view studios/2BRs now disappear instantly at 11-months out year round. Boardwalk view studios/2BRs do the same during that fall season.
