The 712 sq ft for BWV is about correct; studio is about 360. Those BWV numbers that have come from some Disney published numbers are in error. Orginal BWV plans had those larger room sizes. Those plans were replaced before construction. Nevertheless, the sizes of the rooms from those plans keep raising their head now and then. For many years the Disney website published the correct room sizes. Then they had a total makeover of the Disney website about four years ago and when the room sizes came up on new pages, they had the room sizes from the original plan. I think they have removed them now but the error keeps living. Been in both and did not notice huge difference. Sense of BWV could be larger because front foyer, kitchen and shower room in BCV are a little bigger than BWV, and couch is longer, the combination of which make the living room and large closet at BCV smaller than BWV.
