When I have saved points that I know I won't use in time, I sometimes gift stays to friends and family if I don't want to bother trying to rent. I am currently arranging a getaway for a friend whose wife is going through cancer treatment. He is happy for the diversion, working on planning a trip, taking him out of the chronic worry headspace. She, also, is excited, thinking about After I Get Through This... If you look around, probably you can find someone very deserving or in need of free lodging somewhere. And, certainly, ample opportunities to rent out if you need to collect $ on the points.
You could also book something to deposit to an exchange company so you can make the exchange another time, when it will be convenient for you to travel. This is generally my last choice but it is the most generous in terms of timeline to finally use up those points. I book as many cheap weeks as I can to deposit, though others may be concerned about trading power. I think the smallest weeks we have are 2000 points.
Good luck, let us know what you do with the leftovers!
