My post, no. 3,954 above, provides the answer to that question. DVC has developed over the years, two seasons at WDW, the low to moderate demand season that runs from the Monday after marathon weekend in Jan to late Sep, and the high to extremely high demand season that runs from late Sep to marathon weekend in Jan. The demand levels between those two seasons is like the difference between night and day, So when a seasoned member speaks of "busy weeks," he is referring mainly to all the weeks in that fall to early Jan season.
During the low to moderate season, the Princess half-marathon weekend is the highest demand time when rooms fill quicker than they do even for Easter or July 4 time. But the quickness for which rooms fill for that weekend is dwarfed by every week in the late Sep to marathon weekend in Jan period. For 2021, the high demand season added the MK 50th beginning Oct 1. Within 30 seconds after the 11-month window opened for Sep 30, 2021, every room that exists at BLT -- studios, 1BRs, 2BRs, and GVs -- filled for both Sep 30 and Oct 1. VGF 1BRs are usually open even at 7-months out in the low to moderate season. In the first week of Dec, they sometimes fill within minutes after the 11-month window opens.
Thus, when evaluating reserving times, the focus is mainly between the two different seasons. AKV savanna and standard view studios are usually easy to get at 11-months out year round, although there is some risk the standard views could fill very quickly in the morning at 11-months out for the first week of Dec. Kidani savanna view studios are usually open throughout the low to moderate season at 7-months out, with a risk otherwise during the Princess half-marathon weekend. Kidani standard views are also open many weeks during the low to moderate season although they can fill at times. Jambo standard views are more difficult during the low to moderate season and its savanna views, although usually open more times than standard, can still have an issue during many of the weeks of the low to moderate season. During the high demand season, both Jambo studios and Kidani standard studios have a significant risk of filling multiple days a week before the 7-month window opens; Kidani savanna views have a better chance except during the extremely high demand time that I mentioned in the prior post.
