I just want to share this with you since it is a lesson I paid. I made a ClubPass booking for 6 nights 6 months ago for traveling in Dec. This week, I made my flight booking, found out it would be significantly cheaper if I shorten my stay by one night. So I called WM, trying to shortening it to 5 nights. They said, I have to cancel the entire booking and hope there are dates available for the same period again. Of course, there isn't. The system would not allow them to drop night, you can add night, but not dropping. So if I want to keep my flights, I lose the last night point usage. And of course, no one else can book the empty unit because the system would show as occupied. Yes, that is how ridiculous this is.
