It's been said over and over, but I must add my voice as well. Hyatt CS agents are simply the best. I dread making calls to virtually every other service provider I transact with, usually because I end up talking to someone on another continent that is painfully making his/her way through a flowchart without an ounce of rational thought.
It's always a pleasant experience when I call Hyatt. I don't wait on hold. The agents are pleasant and sound like they WANT to be there helping me out. They understand what I'm trying to accomplish the first time I explain it, and they resolve my issue on the first call.
I understand implementing a reliable loyalty system at hundreds of properties worldwide is a challenging task. I hope that Hyatt is planning to make changes to improve here, but in the meantime, I don't have any problem with the customer service-oriented "just call us to fix it" approach.
