thanks, thinktink!
I looked around that site a little bit, and found this about the different rooms that offer MK view:
"NOTE: Magic Kingdom views are found in the Boca Chica, Sago Cay, and Conch Key buildings. Rooms in Sago Cay have maximum peacefulness in a setting far from the pool; however, they also require a longer walk to the main building. Sugar Loaf and Big Pine are closest to the main building and the monorail, but because they are near the courtyard pool, they tend to be a bit noisier."
They don't tell what specific rooms are best, but at least it describes the buildings
