My last 2 trips I have different experiences.
In June 06, the CM, who was earning her ears, looked at the computer and whispered to her boss CM "they asked for xyz and all I see is abc". I was then shown a map and offered 8 or 9 great choices! I made this reservation only 1 week ahead of time if that may have had any bearing. We checked in around 11 am.
In Jan 06, I had requested some of the same things as the OP .. 2 bedroom dedicated, 2 queens, non smoking, upper floor and near the elevator. We checked in around 2 pm. We were already assigned the room and it was perfect and ready! I could not have picked a room that would meet all my requests better!
