I'm half with the OP on this one...

I do like to get the notes. I'd prefer they be genuine rather than some corporate mandate. When it's genuine it makes all the difference.

My work travel plans have me usually going between 3-4 cities all the time. As one would hope, many of the staffers will recognize me and strike up a meaningful conversation. One of the bellhops even jokingly will say, "Welcome Home." Or at a few of the restaurants they'll see me walking in and already have my drink waiting for me and ask if I'm going to order my usual meal. When you're on the road 250-300 nights a year, those little touches DO make a difference.

Now, I recently stayed at chain hotel where they were just finishing up a remodel and I was in one of the newly-remodeled rooms. I dropped a nice note to the manager about a few problems that should have been punch-list items, like a bathroom door which wouldn't close and other sloppy workmanship. I received a somewhat generic e-mail that they would use my input to "improve the product." While I'm glad to get a response, I could do without the corporate marketing / business-school verbiage.
