If they're banked or borrowed, you can't transfer them. You could do a rental that started the last day of Feb by adding to the 4 with borrowed points. If you don't need your transfer slot, you could take a transfer to combine for a single night and just give them away to that person as part of the process. They could then make a reservation for 1 night and link to one they might have already. Those or variations are about all I can think of. I wouldn't use the one time double secret exception to bank 4 points even if you could.Thanks to an add-on purchase, I will soon acquire 4 points that will expire at the end of February. (I have a March use year.) Is there anything I can do with those points other than watching them expire?
