When I called to make a room request, the CM made a point to say that they cannot guarantee we will get our request, but they will try. Room assignments are made 3 days before your arrival, so I called again just before the 3 days to make sure my request was still in the computer. (Somebody had posted that their request got deleted somehow, so they did not get their request.) The 2nd CM also stated that they could not guarantee that my request could be granted, but that they would try. (I'm thinking they get a lot of people who are upset that they didn't get a particular room...)
