Depends on how many are traveling. We actually enjoy the studios. The one bedroom villas are nice tho. I don't think you will find a huge difference in views depending on the room size tho. You could have a studio with a terrific view and a one bedroom with a not so terrific view. We like to save points and stay in a studio since we don't do a lot of cooking. The micro and toaster work great for us. Yes, I love having the washer/dryer in my villa but it usually doesn't take long to go down to the communal one.
While I can't say exactly how large the rooms are at BCV, since we haven't stayed there yet, I can tell you the studios at BWV are about the same size as a regular deluxe room. They feel spacious tho since you have the sofa bed rather than another queen size bed. And the vanity area across from the kitchenette area opens things up. As far as a balcony goes, I believe that most rooms have either a balcony or a patio. They may be different sizes tho. I wouldn't plan on having a cocktail party on one!!!!
