Haven't done anything lately, but about 3 years ago I tried to call the room assigner at VWL on two occasions, and the person at the switchboard wouldn't connect me. I can't recall the reason, but it sounded pretty lame, and I was reading that other people had called directly. (We still love the VWL and bought DVC there, so this was just a puzzle to me, not a big deal.)
I spoke with a wonderful room assigner at the Contemporary 4 years ago, and she was very helpful and gave us a MK view room on an upper floor, as requested. We were already at Disney and just switching rooms, so I spoke with her a couple days ahead.
