On a recent trip, I was given a smoking room, even though I requested a non-smoking room. I called down to the front desk and was told that my reservation did not have my preference. I chalked it up to the new corporate travel agent. After returning home, I found my confirmation which said, wouldn't you know, non-smoking. I fired off a letter to the manager and have not heard anything since.
By the way, my employer practically owns a few suites at this hotel. There are usually 2 or 3 of us there every weeknight. Let's eee what comes of it!
