December is probably the busiest time of the year for DVC, although the period you list is probably not quite as bad as early December or Christmas-New Years.
BWV standard view is tough to get at 11 months, much less 7, so I wouldn't plan on that. AKV will be tough for a while, but once it gets fully built, it will be a pretty good-sized resort and ressies will be easier to get. However, I think you'll have the same thing there you have at BWV -- the low-points units will go to owners of that resort at 11 months.
At other times of the year, you'll have much better luck. We were able to get a BCV studio for five nights (in May) at 5 months out.
I'd make a backup ressie at SSR to be sure you have something, and then see what you can get at seven months.
