If you are booking exactly 11-months out for marathon weekend, you should not have a problem getting a GV at BLT (or any other resort that has GVs other than OKW GVs in the near Hospitality House booking category). For every year that there has been a marathon weekend in the past ten years, BLT GVs have been readily available to be reserved at 11 months out. The only BLT rooms that have been a problem in the past at exactly 11-months out for that time of year are standard studios (and thus also lock-off 2BRs), and standard dedicated 2BRs.
