Not IMHO. There are a few differences in the furniture and of course the theme/decorations are different, but the basic layout is the same. As far as the rooms/layout go, I don't think there is any difference worth mentioning if you are talking about a studio.
SAB is awesome, but it would be easier to keep an eye on your young children at the BWV. BWV also has the advantage of the guaranteed BW views or less expensive standard views,but they are tough to get if you do not have the 11 month booking window.
