As stated above, the WL is decked out beautifully in Christmas decorations that will just take your breath away. Since you are going before Christmas week, you should not have a problem with crowds.
As far as the view, I prefer the courtyard. From our balcony we could see the pool, stream, geyser, and lake. At night you could see and hear the Electrical Water Pageant show right from your deck. You can also hear the nice soft piped in hotel music if you sitting on your deck that along with the sound of the water flowing just relaxes you so much!
