If you are still within your rescission period, I'd STRONGLY suggest that you rescind NOW! Follow the directions on your contract to the letter.
We love our Club Wyndham points, purchased resale for a
small fraction of the developer pricing. If you are able to rescind, do it and save many thousands of dollars! But if it's too late to rescind, welcome to the club - there are many here who have made developer purchases and overpaid. If that's the case for you, learn to make the most of it, beyond the fun, well-appointed Wyndham resorts.

To try for a trade into DVC via RCI...
Go online through Wyndham's website and access the Wyndham portal to RCI.
Click on "MyOwnership" > "Exchanges" > "Search..." > Click to acknowledge and "Continue" (to RCI).
Join TUG ($10?) so you'll have access to the Sightings board where people regularly report seeing availability at Disney's Saratoga Springs Resorts (DVC SSR). That will give you an idea of what to expect for availability.
Developer Wyndham points may be used to book available stays at a DVC resort via RCI - either in RCI Points or RCI Weeks, you'll see both (my resale points can only trade via RCI Weeks). As mentioned, RCI availability is sporadic and it's mostly for 1BR at DVC SSR for a full week. You can place an OnGoing Search (OGS) request and only inventory in RCI Weeks will match to the OGS. The "cost" of an RCI trade into DVC is higher than to some other area timeshares because Disney charges a $190 resort fee to incoming exchangers. But depending on your home resort maintenance fees, it may still be a decent deal for Wyndham owners because it only requires 77,000-126,000 Wyndham points to get a good 1BR week via RCI.
Unlike most other timeshare owners, Wyndham owners do not have to deposit any points with RCI, just to search for an exchange or place an effective OGS request. This "search first" feature is very helpful. If a match to your OGS is found, you'll see an email. Then you accept the trade and they move the needed Wyndham points from your account over to RCI.
We've entered an OGS for DVC resorts and simultaneously made back-up reservations at Wyndham Bonnet Creek (WBC) which is a beautiful, close by resort. If the OGS matches and we still want it, we cancel our WBC reservation and check that the points have gone back into our Wyndham account. Then we confirm the RCI DVC exchange. Sometimes we prefer WBC, depending on who's traveling and how much we plan to visit the Disney parks on that trip. Hope this help!
