Hyatt has announced changes to hotel award category assignments that will go into effect March 18 at 11:01 p.m. Central time. A total of 259 hotels change category, about a third of Hyatt’s portfolio, but this is balanced with an equal number going up (130) and down (129).
You can book future stays at hotels going up in award price and lock in their current price up until March 18. If you have a future stay at a hotel that’s going down in price, Hyatt will refund the points difference to you automatically. They’ll be doing a sweep starting March 19.
