If you still want to use a deeded week in the same year, you have to cancel and rebook more than 30 days ahead of your checkin date. You can easily rebook online, but strangely, you have to call them to cancel. We had reservations in Feb 2020 and had to call them to cancel and were able to rebook in Aug 2020. We got ocean view instead of ocean front, but we were happy to be there. Here's the contact info for deeded week owners.

BTW, if you can't rebook in the same year at your property, you can deposit it in DEX and book another property in the same year or in a future year. There is a fee when you use DEX ($150?), but it is also easy to use online to see what might be available.
