Something not really highlighted in these devaluations is Hyatt has seemed to have fully built out the reward redemption chart for Category 8. Before Category 8 was an incomplete chart that showed standard redemption, and nothing else was given as far as club access/standard/premium suite redemption.
I think the bigger devaluation is that some Hyatt-branded properties (not from SLH or Two Roads acquisitions) are going to creep up to the Category 8, which in turn some properties will slowly creep up another category. i.e. 5 to 6, 6 to 7, 7 to 8.
