I did some quick calculations, based on the room-type allocations from BCV. It appears to me that there will either be 13 or 14 stories of rooms. The ground floor and top floor are for guest services (ground) and mechanical (top/roof - HVAC, fire prevention, etc). It looks like there may be a restaurant, ala the California Grill, on the main building / top. There will probably be a quick service around the pool and another food court on the ground floor (a guess, based on recent other Disney projects). I'm assuming there will be two sides (or views) for the resort - a pool / lake view and a CR/MK view. That is to say there will be rooms on either side of an interior hallway going down the middle of each floor. The "bulges" in the two anterior wings I'm guessing will be the dedicated two bedrooms.
Here's the room breakdown I'm guessing -
90 Dedicated Studios,
180 Lockoff Studios,
180 One bedroom Lockoffs,
48 Dedicated one bedrooms,
193 Dedicated two bedrooms,
Total of 691 rooms. Again, it's based on the BCV breakdown of units because the BCV is shoe-horned into such a tight space just like the CRV's appear to be. The BCV has 282 rooms on five floors. I don't know how many rooms are in the Contemporary tower and South Garden wing, but this structure could easily equal those number of rooms. It appears there will be a dedicated pool for the CRV's.
We will just have to see 1.) if it is built, and 2.) how close my guestimates are . . .
