At the risk of starting a feud, I'll post my anecdotal experience based on our stay at the BW last Christmas.
Bear in mind we had 4 adults and one child in a studio with a day bed, and we'd just come from a 2 BR at Vero Beach...our views are prejudiced.
We found the room to
feel small. By square footage, it shouldn't, but it felt cramped. The entry area is smallish, and with the wet bar area right near the bathroom sink area, it seemed cramped. Maybe because we had left all of our luggage in the 'entry alcove' area and all of our food and film and daily carrying bagage in the wet bar area.
The bathroom is, by any standards, small....I felt cramped in there all by my self while doing, uhm, research with the unofficial guide.
The main room is fairly roomy. The sofabed takes up a bit of room when pulled out, but with that put away, its comfortable enough. The table is pretty small...about a 2 person max, and the daybed was in an area where I'd normally think about dropping luggage.
With just the two of you and a child, the room should be more than adequate so long as you don't sprawl stuff like we tend to do. Filling the wet bar counter certainly makes it seem more cluttered.
With the curtains drawn, it also feels smaller, since the room was pretty dark. Opening the curtains helped expand the feel of the room, especially since we had a great view of the main pool framed nicely between two trees.
Now, from what I've read, the BWV, VWL, and BCV are all alike in general room sizes...OKW is supposedly roomier (by sq. footage) and airier (by design and paint scheme)...From what I remember of the tour we took at VWL when they first opened, the theming of the room might make it feel smaller as there were alot more dark greens and wood colors.
I hope this helps,
Joe
