I had a stay in Maryland over the Labor Day weekend, and today I noticed a charge on my bill that I figured had to be the Diamond breakfast or wi-fi mistakenly being posted to my bill. There were no charges when I had checked out. Quick PM to Hyatt Gold Passport Concierge here on MilePoint and it was fixed in a few minutes, with a response that the hotel would be posting a credit back to my AMEX. I continue to be impressed with both their response times and ability to resolve problems. I've probably had 10 conversations either here or on FlyerTalk with Gold Passport Concierge the last 2-3 years and every single issue I've raised has been researched and resolved promptly. Most of the prior contacts have involved points not correctly posting, though that seems to have resolved itself this year with the bonus points (G1, G2, G3) not in play. Imagine sorting out those transactions took them a lot of time. I appreciate that they're able to help me out when issues about my account do come up.
