As far as I know, there are also a few studios in BCV that are adjacent (though not connected). One dedicated studio next to a lock-off as I recall. In addition, I believe that at some resorts, some of the lock-off studios abut with the 1BR on opposite sides for each studio. We took DFIL to WDW and had two studios at BCV that were directly across the hall from one another. At OKW, we were at opposite ends of the same building on the same floor.
