I forgot what the rules are for cancelling an II exchange? Is there a latest time in advance of a reservation you can cancel and still have use of your week to exchange in flexchange? I have a Marriott reservation for December 2 and not sure I can go. What is the latest I can cancel and still have my week to use in the future? It was a Marriott to Marriott Destination Club exchange so no fees involved. I do remember cancel less than 14 days you can only exchange up to 30 days in advance.
