Are you looking at booking 11 months or 7 months out. If 11-months that means seeking a reservation for sometime in the latter part of July, one of the lowest
DVC demand times of the year, and, with one exception, you should have no problems booking your GV at any time of the day at 11 months (or even many days after) regardless of which DVC Resort you own. The exception is the OKW GV's in the near Hospitality House booking category, which tend to fill instantly at 8 a.m. at 11-months out year round.
If 7-months out, you are looking at third week of March and likely several resorts already have at least some of the dates filled for GVs during that period, such as Jambo, Kidani standard view, VGF, BWV and OKW, and thus you will not be able to get them even if you are the first one online to reserve them at 8 a.m. at 7-months out. Other than BLT, if not yet filled for any of your applicable days, there should be no problem at 7-months out, at any time of day, getting one of the remaining resorts that have GVs -- SSR, Riviera, CCV, and Kidani savanna view. Thus, BLT is probably the only resort where, if rooms are still open, that the issue of booking right 8 a.m. may be important. For that one if dates are currently open, you might consider a walk by booking some nights right now, and then walking ti the actual time you want (with the understanding that walking has a real risk of not succeeding at 7-months out because an owner of the resort can book the days you want at any time.
Also note that if you are actually considering Kidani, you may want to change that. During March 2022, its pool will be closed.
