Biggest single reason to keep or to not keep it would be the possibility of exchanging into DVC (at any property, we love them all). We plan ahead and can travel almost anytime and are fine if it's SS 3day/4day/7day.
308,000 biennial; MF $700 (so $1400 for the lump of points).
We have modest interest in using home resort, but knowing it was possible to exch into DVC would make the ownership far more valuable to us.
This is key. With Wyndham, it doesn't really matter much which Wyndham is the home resort, since you are able to plan ahead and have a flexible schedule. BUT, would you be happy to use those points to stay at various Wyndham resorts if DVC stopped trading through RCI and you could NOT try for a trade there? Since you would be committing to ownership of a Wyndham contract, you need to be sure you would be satisfied to use it at Wyndham properties. Please feel free to PM me if you would like to discuss further.
Regarding the current situation with DVC exchanges (subject to change, of course), those are nice, low maintenance fees, just $478 for a 105K 1BR week. So if you add the current RCI $239 exchange fee and the $190 resort fee charged by Disney to exchangers at checking, a 1BR week at DVC SSR would cost you $907 total (no taxes required). This is a nice number - just subject to change. [Unfortunately, a 3-, 4-, or 5-night exchange would cost the same, so don't consider those.]
We have found it fairly easy to trade into DVC SSR 1BRs with a flexible schedule and early OnGoing Searches (OGS) through RCI. Holiday weeks are generally out of the question, and you probably already know that it's not easy to get popular festival weeks in October, RunDisney weeks, or weeks during Spring Break - although may be possible. But that still leaves a lot of the year.
You can RENT Wyndham vacations cheaper than owning a few hundred thousands of points, paying $6-7.70 per 1K of points in MFs yearly, paying for "Housekeeping Credits" and "Reservations Transactions" PLUS the $99-129 each Guest Certificates.
Given the further details posted by the OP, I'm not sure that much of this would apply to the OP's specific situation. In my 20+ years owning (resale) Wyndham points, this has not been my experience either. It really depends on the contract(s) owned, MF, usage style, etc.
For the OP, your cost for a 1BR RCI exchange using the Wyndham points, including $239 exchange fee, would be:
$589 off-season 1BR trade for 77K points
$717 popular season 1BR trade for 105K points
$812 prime holiday week 1BR trade for 126K points
...all subject to change with increasing MFs and/or RCI exchange fee.
