First. When you get the email for the survey be sure to complain and explain. Letting them know of the hardship and difficulty it caused you. You did not say how many nights you stayed.
I have not stayed a Hampton Inn that I never got a survey email. My wife and I almost always stayed at a Hilton Hotel. That was until I lost over 250,000 points. We were saving them up for a Honeymoon we never did take. And well, I did not know that you could lose them.
But I have had several Hotel managers offer us points or another stay, I even was reimbursed once.
We have found the Holiday Inn very competitive, and we have found the La Quinta’s the cleanest and friendliest chain we have stayed at.
May only other question would be did you go through Hilton Honors to book the room. If you did you should have no problem. If not that is where it says in the little tiny print the agency is responsible.
