Riviera is still not a sold out resort and what I mention here could get worse as sell-out is achieved.
Owners of a
DVC Resort can book up to 7-nights starting at 8 a.m. eastern 11-months out from date of arrival. Riviera standard view studios (and also tower studios) have developed somewhat of an 11-month issue, where they can book full within moments after 8 a.m. at 11-months out, with the result that some owners can fail to get a standard studio even if trying right at 8 a.m. at 11-months out.
Thus far, that 11-month issue has been mostly limited to the extremely high demand times of the year during the high demand "fall" season, which runs from late Sep to marathon weekend in Jan. The extremely high demand times, which have shown a risk for Riviera tower and standard studios booking full right at 8 a.m. at 11-months out, are times during first two weeks of Dec, Christmas week, the Nov and Jan race weekends, and time around Thanksgiving. However, it has also happened, rarely, at other random times of the year.
