We are a family of four and found the room size and storage to be fine. The closet is ample space and the drawers provided were enough to unload all of our stuff. There are also a couple of small drawers above the fridge. The regular queen size beds had a solid base, so you can't put anything under them, but we had bunk beds in our room and we could put stuff under there.
I'm not sure about rooms with a lake view. We had room 7042 which gave us a great view of Cinderella Castle, it was awesome! It was also on the end of a hallway so no one on both sides of us. Very quiet.
Enjoy your stay!! WL CL is awesome!!
