Actually there is construction going on in the South Garden Wing... it's been cleverly disguised. In the central elevator area, where the seating and parking access are located, there is a door on the same wall as the elevator, with a sign noting "Cast Member Access Only" and directly below that, a list of room numbers. Beyond this door are the rooms currently under rehab.
I too have recently stayed in the South Garden Wing... was not impressed with the room and level of service, considering we were paying rack rate, and frankly, even if we had been paying half of that, we still wouldn't of been satisfied.
