In my experience (and that of several others) BWV is NOT GOOD at meeting requests. Ask, it never hurts to ask, but I wouldn't set expectations at getting it. We've had a request met once in six or seven BWV trips....and that was a request to have two rooms close together where the note on both reservations said "cancer recovery trip."
I don't think the front desk necessarily has a good idea of which rooms fit which request criteria if they are assigning at the time - our two "close to each other" rooms were right next door, but because they were two bedrooms with studios attached, the front desk clerk couldn't tell that and warned us that "they'll be close, but I don't know if they are next to each other." At VWL we had a CM who couldn't (or wouldn't) tell us if our room faced the lake (it did) or the parking lot. And sometimes the rooms are pre-assigned.
