It's a big hit to anyone who has taken advantage of these awards in the past. I'm really just disappointed that Hyatt seems perfectly comfortable sweeping this devaluation under the rug. Of course, the bloggers won't be making a scene about it because this story doesn't help them pimp credit card sign ups.
I always thought Hyatt was transparent about devaluations. Hopefully this isn't a sign of things to come in the future.
