Unless there's something really wild going on, you should have no problem booking your home resort at the 11 month window.
You probably won't have a problem booking other resorts at the 7 month window in general either. Again, time of year you travel may impact a bit sometimes.
Often, what I do is book my home resort at the 11 month window so I ma sure I have a place to stay. Then, at the 7 month window, if I want to stay elsewhere, I try to book or go on the waiting list.
Last Fall we wanted to stay at the Boardwalk in a 2BR to be close to the Food & Wine Festival at Epcot. At the 11 month window I booked a 2BR @ OKW (my home resort). At the 7 month window, I started trying to book at the BWV. I got 3 of the 7 nights I wanted right away. I went on the waiting list and slowly but surely I got all the nights I wanted at the Boardwalk. Now granted, the last night came through the day before we left, but even that...worst case scenario I would have stayed at OKW for one night then moved to the BWV...not too shabby.
Don't worry, booking is generally never a huge problem.
