My wife and I are not big fans of "the view" from the room... for us anything will do. We don't spend much time looking out the window or sitting on the balcony/patio. At any rate...
At WL, there are 3 room views available. The Standard View generally faces the parking lot or driveway and sometimes the roof of another building. Some people have reported views of the dumpster area at WL. From the balcony, you may see trees or pool, if you lean over (but not too far!). This is the least expensive view.
Woods View faces the woods towards the MK (maybe obscured view of MK over the tree tops and maybe a glimpse of a monorail, these would happen only on the 6th or 7th floors, I'd think) on one side and the Wilderness Lodge Villas/woods on the other side.
Courtyard View looks out over one of the pools, the WL courtyard area (the falls but you also see other buildings) or Bay Lake. On the upper floors (6 and 7), you MIGHT see some MK fireworks. On our last trip in May, I noticed the trees around WL have grown considerably, so I wouldn't count on a completely unobstructed view. Obviously, this is the most expensive view. However, on our last trip in May, the front desk upgraded us from woods to courtyard view -- no charge. That may be possible at check-in, but it would depend on availability for your entire stay. We had a wonderful room on the 1st floor with a beautiful view of the falls, pool and walkway to the boat dock.
