It's not realistic or reasonable to blame Hyatt for fire alarms. That's pretty clearly an exceptional situation. For me the internet at most hotel chains : Hyatt, spg, Hilton, Marriott, etc. Is usually ok, seldom stellar, and occasionally poor.

I've had some bad (but mostly acceptable ones) experiences at individual Hyatt place, four points, Holiday inn, Hampton, Fairfield...all chains lower end options really.

As long as Hyatt has acceptable options for work travel and attractive options for your leisure travel and points usage, you will make globalist, and enough stays will be FS to enjoy the in hotel benefits, they are a top choice. It's up to you what acceptable is, and what constitutes enough fs stays.

In particular earning/burning rates for high end properties are quite good, as is the quality of top properties.
