You need to remember that the DVC member "owns the reservation" and any communication to MS has to be through them. MS will not speak to to you about anything. The member can also set up ME for you.
Since you're renting points, the number of points used by the DVC member to obtain "your orginal room request" through David's has already been done by the DVC member. Different views, different seasons, and room types all require a different number of points to be used. If you are wanting a very specific view like a MK one, and you asked for a standard one, then you will need to contact Davids again and request them to contact the member and see if they can get that for you. Chances are it will cost more points for the member to do this if available, and therefore an additional cost to you. In the DVC world, you get the room you requested orginally based on the points used, unless you put forth more points to get a better room type or view if available.
