In the past, before the addition of the new rooms, studios at VGF, both standard and lake view, filled right at 8 a.m. at 11 months out for any given start date (or even before due to multiple day reservations), for some of the times in the high-demand late Sep to marathon weekend in Jan period, but for other times were usually available at least long enough to easily reserve them as an owner if you booked at 11-months out. Standard view 1BRs also had an 11-month issue at times during the first two weeks of December and time around NYE.
As noted, there could be upcoming changes in patterns as result of the addition of the new rooms. Another factor that could change patterns is the annual point shifts that DVC has done in the last few years, e.g., first two weeks of May are now a low-point season and might develop much higher demand than previously.
