I have been looking at this rendering, and I think I have figured it out. It looks like it will be T shaped as we all assumed. It looks like this was drawn from the vantage point of looking from the existing pool area into one corner of the T. The walk way on the right (thru the building) makes sense since there was an existing access point from the front of the hotel that would be blocked if they did not allow for the walkway. The part of the building on the left of the photo is clearly
DVC (Notice the lack of a balcony in on the master bedroom part of the villa). It is one floor shorter than the other section because this part of the building is most visable from DCA. (I assume to reduce visual intrusion into the park) This part of the building that we see faces the pool area. The other side will face DCA. This means that they are giving DVC the better views. THe part of the building on the right are standard rooms, as they will blend in better with the existing structure. This is speculation, but I am fairly sure that this is correct.
