Is it difficult to get other DVC properties beyond the 7 month mark?
The only serious shortages I've ever heard of are for the larger rooms that are only available in relatively limited numbers, such as the 2 BR and 3 BR villas. Getting a 1 BR or studio shouldn't be a problem for any DVC resort at the 7 month window, unless you are attempting to book during an event that causes a property-wide booking surge, like the marathon in January.
Not sure if the 7 month versus 11 month window makes sense, but you can only book up to 11 months in advance for your "home" resort(s), and up to 7 months in advance for the other DVC properties.
Note that this window is to the exact day, so when booking a multi-day stay during an insanely hard to get time (say near Christmas, and you want a large room), you'll have to call up every morning when their reservation center opens and extend your stay one day at a time (or three days when calling on Monday)
From personal experience, you have to be pretty fast on the phone to get a grand villa at that time of the year.
Then again, your mileage may vary, as I've only booked rooms in 3 of the DVC resorts (and only one of those actually at WDW!)
