I was there last week (checked out of AKV concierge on the 24th and moved to a GV at AKV), and they are sandblasting and painting all over the outside of the resort. They weren't working on the sixth floor rooms yet, but they were everywhere else.
There are skytrak-type lifts everywhere, and they seem to be focused on painting the large "logs" that go up all along the outside of the buildings.
