I actually did that yesterday. I am traveling on New Year's Eve and New Year's Day. Both stays were with Hyatt. I still cannot get into my account and nobody seems to be able to help me or call me back. But on the website one can pull up reservations and cancel without getting into their account. So that is what I did. I'm sure they will still sell out of rooms for these nights anyway, but I have some degree of satisfaction with my decision. I rebooked with Hilton.

My only real question is did the Goldpoints make it back into my account? I took screenshots of everything. Hopefully in a few more weeks they will clean this mess up. I may also call today and see if "they can see" that the Goldpoints were redeposited. If they are unable to tell me that much, then I'm going to assume that my account was wiped.
