I moved your post to it's own thread, and deleted your specific date/resort, so your post would not be perceived as a virtual Ad.
In the TUG Marketplace (TUG Classifieds) we have a section where you can request private trades. The link for this area is in the red bar at the top of the page - Ads are free for TUG members.
That being said, you are probably trying to trade-up, so it may be hard to find a taker. DVC is one of the highest demand trades out there, it's expensive to own, and they are highly prized by their owners.
The best way to get a DVC exchange through RCI is to put in a very broad request (many dates) a year or 2 in advance.
If you are asking for one week in Feb. - especially President's week, or any school holiday, your chances are slim and none.
Another option is to rent your timeshare, and to apply the funds to a rental from a DVC owner, and rent exactly what you want.
