If something doesn't work right, always mention that during the stay or check out (and email the manager of the hotel). They've always taken care of things.

I had some issues at Park Hyatt DC (charged for 2nd person's breakfast and I had to ask them to remove it, didn't leave a rollaway bed in the room). For that, they gave me 40,000 points (had a 2 night stay so the premise by GM was to erase the cost of those nights as each night here costs 20,000 ... although mine were paid).

At Park Hyatt Toronto, one night stay, we had a bad experience during breakfast where the service was just bad. Plus there was a hole in our comforter. 15,000 points given (again, this was to erase the cost of staying there which was 15,000 points but mine was paid in cash).
