As DisBuckMan said, it sounds like you are talking about renting your points, in other words, making a reservation with your points and renting that reservation to someone. If you advertise your points for sale, people will think you are selling your contract.
If you book a reservation and try to rent it, you have to find someone who wants the exact dates, resort, room size and booking category you reserved. If you just make your points available for rent, you will cast a wider net.
