I was just there a couple of days ago.
They are working on a lot of buildings right now:
11, 12, 14, 15, and 16.
I assume they were working on 13, but I couldn't really tell.
18 was unoccupied, but looks like it has been completed. All the lights were on. I assume they are just doing the final things (like housekeeping, etc) before they open it back up.
The only thing open at that end of the resort was the check-in desk.
ps I had a 1-br unit. Because 11 and 12 were closed, I had a unit under a grand villa in bldg 30. I for one really liked
the refurbished rooms, although I don't particularly like being under a GV.
