This is kind of the inverse of what many people ask...which is "are there times of the year when it's hard to get 7 month reservations".
I'll start by saying that we've done reservations twice at the 7 month window at non-home resorts with no problem. Once was during the summer and once during Spring Break (a very busy time). We did call day by day for the second one.
Even though low point times are popular with
DVC members, the peak times are still very busy as far as I can tell. Even with the high points, there are many willing to go during those times.
I think if you're flexible with your dates, or locations, or accommodations you can get reservations at the 7 month date most of the time. But if you have your heart set on a BWV Standard View during W&F Festival...well, you'd have to get pretty lucky.
