I agree with PHLGovFlyer.
However, if you've cancelled after the reservation's cancellation deadline, then you might still be charged whatever costs were outlined in those cancellation terms. You should still get your points back, though.
If this is the case, you could ask the hotel to waive the cancellation penalties or perhaps negotiate an arrangement to reschedule your stay. But I think it's all up to the hotel at that point -- not SPG.
