I agree with VA1379 that it is always best to address a situation while you are in the property especially any type of situation that is easily remedied like noise or housekeeping. It gives them a chance to fix it, plus if it continues it certainly puts a damper on a vacation mood - who needs it.

The concierge situation is a little different - I am not sure how I would have handled that one - you feel like a 2 year old asking for a manager and then saying "they are being rude to me"! I probably would have asked why my desk wasn't open, or why in the world one tower had 3 associates and mine none, or some situation thereof.

I do understand your feeling about the letter. It seems as if you would just like your concerns to be acknowledged and addressed....which the 3 lines and points did not do.

If I were you?

I would write again, saying that while you are most appreciative for the 10K in points (and that's not too shabby an amount IMO); that isn't why you wrote the letter, you are still blah, blah, etc, etc, yada yada. I think you should include the fact that you felt as if you got a form letter and a brush-off. If you sent the first letter to the hotel itself, I would send this one to corporate. That sends a clear message that you believe this is a problem and not merely a hidden request for points.

I think some properties have gotten into the habit of throwing points at "problems" to make them go away. Of course, to be fair, they have gotten into that habit because there are so many complaints made just to get points - it has become a vicious circle!

If you truly believe that your issues are valid and need to be "heard" - this is your only recourse.

Would it be easier to just drop it? Of course. Will you feel better or worse - only you can decide. Should you have to write a 2nd letter? No, but....
Is this Marriott's normal behavior? Has not been for me, but I am sure there are others who have had the same experience as you.
