Had one experience that may help. Find out where the room is as exactly as possible before you leave the front desk. If you don't like the location, say something! I checked in late one time, and didn't want the room they assigned me, only because it was first floor and as a woman traveling alone I really wanted an upper floor. Very nicely I asked the CM if there was PLEASE anything upper floor available. Well, she looked on the computer and found me another room, saying "Hmmm! This one has a nicer view, too. I wonder why it wasn't assigned to you in the first place?" Sometimes there's another room available-people didn't show up or something.
