Value studios (there are 18) have had an 11-month issue for a number of years now and it keeps getting a little worse annually. Getting one at 11-months out during the high demand season from late Sep to marathon weekend in Jan is very difficult. Also difficult during rest of year but chances at times develop. Moreover, even walking can be difficult because of the difficulty of finding a day on which to begin a walk.
Nevertheless, the value studios are only the third hardest DVC rooms to get. The AKV club level studios (5 total) are the worst of them all, typically disappearing extremely quickly at 8 a.m. at 11-months out (or shortly before 11-months out) most of the year with minimal chances even during the lower demand times. The second hardest rooms to get at 11-months out are the OKW Grand Villas in the near Hospitality House booking category, of which there are only 2.
The fourth hardest rooms to get are not at WDW; it is the standard view GV's at Aulani (2 total). And number 5 is the boardwalk standard studios (about 39).
A distant Number 6 used to be the BLT standard studios (typically a problem at 11-months out mostly just during the high demand season but does occur at times during the rest of the year) but that is now being overcome by the Tower studios (which are likely to become as bad as the AKV value studios), which has also resulted in BWV boardwalk studios moving down to 8th. Hotel rooms at Aulani are ninth. CCV standard studios come next, and number 10 is VGF studios, usually only for a limited part of the high demand season.
Am I just extremely lucky then? I was able to grab a full week at BWV Standard Studios for the week of Aug going into Sept. and I have AKL value studios for 5 days in Nov.
AKL club and AKL 2BR value has been elusive for me though..
