Nobody knows. Consider yourself lucky if you're able to get them all in the same building.
Keep in mind that
DVC is very flexible. It's not like everybody is checking in on a Friday, and everybody else is checking out that same Friday, as you'll find with fixed week timeshares.
It will depend a lot on the day you're getting there and how many check-outs are being done. The only villas available will be those with people checking out the same day you're arriving.
Not that many use the 2-B/R unit, so a lot of them are being used as a 1-B/R and Studio by separate parties. To get it back to a 2-B/R, both parties would need to be checking out on the same day.
Often on these boards we don't think that much about room assignments, but the logistics of it is really quite complex when you think about it.
All you can really do is put in the requests and hope for the best. Keep in mind requests are prioritized top to bottom, so you'll have to balance that request with your other requests such as non-smoking/smoking, ground floor, DD view, etc.
Make whatever is MOST important to you your top level request.
