The Hyatt Regency Aruba has a history of playing games with free night award availability. They made it nearly impossible to spend Hyatt points, assigning only 22 out of their 357 rooms as potentially eligible for redemption. This hotel is actually owned by Hyatt, and after I brought their shenanigans to corporate’s attention they adjusted the practice.
However Aruba redemptions again became a problem. Some time in the second half of December all award night inventory at the property for 2023 zeroed.
