I have a hard time believing that 60 nights versus 25 stays makes all that much of a difference to lounge/breakfast/suites. Why? Because 25 1-night stays weren't really spending all that much time in Hyatt hotels. And the travel hackers amongst them were probably in Vegas hopping between Excalibur / Luxor.

I suppose that a possible exception is that 25-stayers were also staying on points in NY, NOLA, etc. and without Globalist status those people are shifting their Chase points elsewhere.
