While the benefits of Diamond GP membership can be appealing, I'm finding my recent experiences with Hyatt.com's flakiness and the inability to manage/cancel stays using points without calling the GP desk to be more trouble than the benefits are worth. Has anyone here pondered this tradeoff? The last straw for me has been a recent episode in which my fluid travel plans incurred several iterations of cancellations (and yes, I called the Diamond line each time). Long story short, one cancellation did not return points to my account (resulting in my having to follow up and call back) and, worse, after a series of other bookings/cancellations, I seem to be out 5000 points because the bookkeeping of points in GP's system doesn't agree with my tracking of points balances. I have neither the patience nor time to argue with a GP rep about this, but there is absolutely a frustration; even if this got resolved, the hoops through which I have to jump (to stay atop matters) no longer justify the rewards of the program. This is an issue I never have with other chains (principally, because their web presence and processes both allow users to manage these activities independently and reliably track points-based transactions). I'm interested in hearing anyone else's take.
