That compensation was more than likely from a call received, complaint recorded and sent for follow up. As far as I know, post stay surveys are just used to evalute hotel star ratings and see if they need to be adjusted down. And I honestly agree with Kade. If you have a reservation and you call in a week later saying the hotel was horrible, you're not liable to get much consideration. After all, how bad could it have been if you didn't call immediately. You're best bet of getting assistance, is to request to see your room before checking in. If there's something seriously wrong with your room or the hotel, call in immediately and explain the situation.
