DVC actually announced several years ago that it would not accept location requests for AKV value rooms. Nevertheless, once in a while someone reports being allowed one. The reason that has occurred is likely happenstance rather than any change in policy -- the particular MS person contacted just does not know that particular value room rule.
A request DVC does accept is for a dedicated studio (one not attached to a 1BR). That is a request, which if granted, would avoid the parking lot view value rooms because none of those are dedicated studios. There are four dedicated studios overlooking the savanna and four the pool, so your chances of getting a savanna view if the request is granted is 50%.
