Update 3/27/23: Award changes go into effect tomorrow.
Hyatt has announced award changes for 2023. There is a spreadsheet found here for easy sorting. The main points are as follows:
Changes will go into effect on 3/28. Book by then to lock in pricing, if you book a property that decreases in price you’ll be automatically refunded.
214 properties will be moving up categories and increasing in price
158 properties will be moving down categories and decreasing in price
Seems like the worst hit properties are the all inclusive ones. Feel free to share your observations in the comments below.
