Yes, you can generally cancel a Hyatt Free Night Award reservation, provided you do so within the specific hotel's cancellation window. In 2026, most Hyatt properties require a 24-to-48-hour notice for a penalty-free cancellation. If you cancel on time, the Free Night Award (whether it’s a Category 1-4, Category 1-7, or Milestone reward) will be automatically redeposited into your World of Hyatt account. However, you must be extremely careful about the award's original expiration date. If you cancel a stay that was booked with an award that has since expired, the award will be lost and cannot be reinstated. It is always best to check the "My Awards" section of the Hyatt app before canceling to ensure your certificate is still valid for future use. If you cancel outside the allowed window, the hotel may charge a "no-show" fee or forfeit the award entirely depending on the specific rate terms.
