The reason I said I have a week to decide in my earlier post is because if the current policy of putting points back into their use year stops (presumably when they open) then those points all go in to holding unless I cancel prior to 30 days before my trip. That means they must be used by the end of my use year and I can only be book a room 60 days in advance. For my family, this would essentially mean losing those points. This is not true for everyone- some people can and will travel in time to use the points. For me, canceling at 31 days allows me to bank those points into the next year. It might be worth reaching out and checking with your owner to see if they have an opinion. Especially since the 30 day mark is coming up for your trip.
