I've stayed in this group of BW view studios - xx29 and xx31. Great view, 31s not as obstructed by the GVs nearby (pillars). They are centrally located along the BW view hallway and have no rooms across from them (less noise if you're a sleeper!).
They are dedicated studios and sit directly above the basketball carnival game, near the Big River Grille.
One floor in this group has an extended balcony/terrace. Also there is a stairway out to the Boardwalk right near it.
One year I had the fifth floor in this grouping and the view was beyond gorgeous.

I've done a myriad of standard studios and had some fantastic finds. However, a lot has changed due to the growth of the trees out front.
I would now request around the far side, near the tennis courts to avoid the possibility of a tree view. And by tree view I mean blocked by a tree, not a lovely greenery scene! Smiling.

You didn't ask about Pool/Garden view. But the Village Green area, BW side of the resort is a great stay. It is almost all studios in that area, extremely close to the lobby, and you get a partial BW view. Great if BW view or Standard are fully booked. And great booking on its own merit, if you get your request, to have very easy lobby access.
