Call the AP hotline to ask about this. We've been able to apply unused tickets toward an AP renewal in the past, but I've heard from other posters that this is no longer allowed. Some people have posted that unused tickets can be used to purchase a new AP, but not a renewal. Can't hurt to check. Also, at least try calling to ask about a refund. We asked about this several years ago, spoke with a helpful CM, and received a full refund. So it can happen, but each case is different and there are no guarantees.
