With covid right now a lot is difficult to predict. Many members accumulated large amounts of banked and regular points and are now using most of them, with the result that 7-month out demand for all times is higher than usual.
However, in normal times, what there has been are two distinct
DVC demand seasons at WDW: (a) the high to extremely high demand time from late Sep to Marathon weekend in Jan; (b) the more moderate season from the Monday after marathon weekend in Jan to late Sep (yes, it is not necessarily holiday times versus others -- e.g., first two weeks of Dec make the Easter weeks look like the slowest of off-seasons -- and the DVC patterns are not the same as Disney in general patterns at WDW). Typically, it is much harder to get rooms during the high demand season at 7-months out than it is during the moderate demand season. For reviewing what studios,1BRs and 2BRs are typically open, mostly open or mostly filled, or filled at 7-months out throughout the year, go here and study the charts that begin a little ways down the first page:
