Can the OP request a specific view with an exchange?
You can request a location within the specific view category to which your exchange was assigned. You cannot change bookable view category---that is fixed at the time of exchange. So, for exchanges assigned to the Preferred view category, you can request *within* that category, but you cannot ask to switch to Standard or Boardwalk. As mentioned, BWV seems to only deposit Preferred.
Edited to add: at other resorts with bookable categories, AKV seems to deposit only Standard and Savannah, and OKW seems to deposit only General Resort. BLT has not been known to deposit, but I assume that when the time comes, it will be mostly Lake.
So an exchange can be booked at the 11 month window like an owner of that resort?
Availability is determined by whatever
DVC is willing to deposit. I have seen deposits as early as 11 months to the day, but no earlier. It is to DVC's advantage to deposit inventory earlier than the seven month mark; RCI begins to penalize deposits at nine months prior to use.
It appears that the deposits are done by hand; they tend to "bunch up", but not in as regular a way as they would be if it were automated. DVC tends to deposit things that are lower-than-average demand internally, but not exclusively so---you do see some holiday weeks and other "hard to get" things show up, but they are less common than random chance would suggest. It is not known whether deposits are drawn from the Member's home resort exclusively, or if DVC has some flexibility in choosing. Presumably, if a Member asks to make an exchange, DVC would follow the same rules for selecting deposited inventory that the Member would be subject to if that Member were reserving to deposit. But, I don't think that is known for sure either.
