We didn't have any problems getting a 2 br at BWV or SSR on our last trip. Neither one is our home, but we did book them about 6 months out and had to be slightly flexible with our dates. BWV was a lock off, but SSR was dedicated.
You don't mention which resort you would be looking at getting into, but you should consider that BWV and BCV would probably be more difficult to get into because of the Food and Wine Festival going on at Epcot. The others, especially OKW and SSR are larger and would probably be easier.
I've heard that because of the popularity of the Food and Wine festival, BCV and BWV can be tough to get for Oct or Nov at 7 mos out. You could probably get SSR or OKW at 7 mos out for Oct or Nov since they are much larger.
You could always use the waitlist. I have read many people's success stories on these boards with waitlists.
What is your home resort? You could always book it at 11 mos and then call at 7 mos and try to switch your reservation to another resort. You don't mention which non-home resort you'd be trying to get. There are probably others on these boards who can help you more if they knew what resort you'd be trying for.
