Except as a non-US resident you can't take out the special DVC insurance.
This is the significance of your Use Year. You need to ensure (as much as anyone is able to) that if you need to cancel your trip you can still do something with the points. This happened to us when we first bought - we were able to recoup not from insurance but by renting our points to others. If its at very short notice all you can do is try to rent out the time you have booked to others.
