It realy depends upon your personal preferences. There are 5 bus stops scattered throughout the resort, so youu ar never really far away from the bus.
If you will have a car, I would avoid the buldings closest to the main pool and Hospitality areas, as their parking lots can get crowded.
While some balcony views are nicer than others, none are "awful."
I know this doesn;t help much, but if you have a car, one part of OKW is pretty much like any other. There was a design change, thoguh, during construction. If there will be someone on the sofa sleeper, the only way into the bathroom is through the master bedroom in buildings 29 and under. There is a second door into the bathroom, through the laundry room, in bldgs 30 and above.
Also, there are no elevators except in buildings 62, 63, & 64. But the parking is also not too great in those buildings...so overall we prefer the Turtle Pond area or the canal view buildings 45. 46 or 55.
