I assume since you posted this in the HRC forum you have booked an HRC week in January with HRC points. If not, you can ignore.
There are 2 thing to consider.
1) If you cancel a reservation more than 2 months before, the cancellation will not restrict your points. So you have some time to cancel. But you will have the privilege of having to pay a cancellation fee. If you cancel with less than 2 months before checkin, your points will become restricted.
2) It matters where the points you used to book this reservation came from. If it is your HOME reservation (a 3br unit in Jan where you own in the week you own) and you cancel, then they not have any restrictions. But if you used points that expire/go LCUP before you cancel, and you cancel, they will become restricted (LCUP) or expire completely.
