Yes, you will get your Marriott Bonvoy points back if you cancel an award stay, provided you do so within the hotel's specific cancellation window. Most Marriott properties require you to cancel at least 48 to 72 hours before your scheduled arrival, but some resorts and high-end hotels may have stricter policies of 7 to 14 days. If you cancel "within the rules," the points are typically reinstated to your account almost immediately. However, if you cancel after the deadline, you will not only lose the points for the first night (or the entire stay, depending on the policy) but you may also be charged a "No-Show" fee in cash, which is usually the equivalent of one night's room rate. For reservations made using a "Free Night Award" certificate, the rules are similar: the certificate is returned to your account if canceled on time, but it will retain its original expiration date. Always check the specific cancellation policy in your confirmation email, as "non-refundable" or "prepaid" points stays are becoming more common in 2026.
