I stayed in a dedicated 2BR on the fourth floor in an area where that was the top floor. I didn't feel the room was dark at all. The only thing I did notice being under the eaves is that the queen bed closest to the balcony in the second bedroom had a shorter headboard than the other bed to be able to fit against the wall.
I really liked our room. It was at the end of the hallway (but the hallway was short). The balcony overlooked the walkway between the WL and VWL (so it faced the front of the resort, not the pool or water side), but over to the right was a nice view of the main lodge.
