AFAIK, the only thing you can do with those points is try to reserve a stay at one of the DVC resorts. Not much time left until the end of the month and availability could be a problem. If you cannot take a trip before the points expire, you could try renting the stay. You'll probably have to offer a very good price to get someone to bite.
Another option is to donate the stay to charity. Maybe someone can post the details of how to do that - I know there were threads on the subject, but I can't find them.
You might also call MS and see if it is possible to do a late deposit to II (Interval International / World Passport Collection) with those points. I'm not sure if that is within the rules, but it is worth a phone call to find out. If Dean is reading this thread, he might know.
I would try to to rent them. People taking sudden trips would love them. They could go for a week to a 2 bedroom! The going rate is 10 dollars per point which is cheap. If after a week there are no bites I would donate them.
Good luck!
