We've stayed in many of the Disney hotels, and actually, our two stays at the Movies have been VERY QUIET. We were in Love Bug & 101 Dalmations (both were the week AFTER Thanksgiving). We never heard our neighbors.
We've also had good rooms at Port Orleans (twice) and Contemporary North Wing. Our room at the Coronado Springs was very quiet, and very convenient to the first bus stop! The Polynesian room was also pretty quiet considering it was right by the entrance door to the building. We loved our room at the Grand Floridian, and although we never heard our neighbors, we did hear people passing down the hall talking rather loudly before 7:00 AM!!!
I don't think its so much the room is noisy - but if your "neighbors" are inconsiderate - either in the room or when they're passing by.
