I wrote a complaint letter to Hyatt Customer Service about a couple of problems I had with the heating system in my room during a week long stay in Denver earlier this month. I got a call from a Hyatt rep within a week of writing the letter, and she was very apologetic about the problem and offered appropriate compensation for the problem (in the form of Gold Passport points).

I oculdn't be more satisfied with the way Hyatt dealt with the situation. I held them in pretty high regard to begin with, but they just went up another notch in my book.
