I had a similar situation earlier this year. I responded to the "How was your stay?" e-mail, noting that the property, one I have stayed at a number of times in the past, was beginning to show its age. I detailed the issues I had with the room, none of which was terrible, but noted that if improvements were not forthcoming I might be looking at staying elsewhere in the future.

I received the same message as EastBay1K, but never received an e-mail or call from anyone after that. I didn't follow-up as I was not interested in a formal complaint in the first place, but only ensuring that the GM of the property was alerted to my concerns.

It's disturbing that Hilton/HHonors, or perhaps the GM, is apparently not following-up these items. Why bother asking for my opinion if you are not going to address it? I would suggest taking your issue to Adam Burke, but it's not clear if he (or his staff) continues to follow any of the HHonors threads. That too is disturbing....or maybe I just have a bad taste from the STILL unresolved issues of the rolling tier qualification mechanism.
