It's supposed to be done by September according to a posting from a member who attended the DVC meeting last December.
When we were there last December, the only Boardwalk section to be done was the Crest of the Wave, they were just starting there. They were working on half of the main pool area, that maybe done by now. The quiet pool area was done first. They were working across from the tennis courts, that should be done by now, they still need to do all of the rooms facing the driveway.
