BWV owner here. What time of year are you planning on traveling? Having owned at BWV since the last 23 years, I want to say nothing is guaranteed.
I used to get what I wanted at 11 months - standard view. Now I have to work hard to get that and sometimes I don't. Especially October to February. Right now I'm struggling to fill in one night for next December - in a garden view room. Standard and Boardwalk Views were gone so fast - at 8:01am 11 months out!
Looking at availability at any resort from now through June of 2023 it's slim pickings anywhere. But at least for most resorts other than BWV, rooms are available at 11 months, even at BCV, as we approach 2024.
I am one that will suggest if you want easier booking, buy almost anywhere but BWV.
