It is not necessarily the room size, it's the time of year. At 7 months out for time from shortly before NYE to about Jan 3 is very high demand time (you are talking second highest demand time of the year) and includes the highest demand night of the year, NYE. You might get lucky and find an AKV GV, OKW GV, or treehouse, but don't go into it with any high expectations. Also understand you might not even have back-ups to get. SSR GV will have a higher chance of being open along with other rooms at SSR and OKW and possibly even standard or savannaq view at AKV, but you could be blocked out completely at BLT, BCV, BWV, VWL, and VGF.
