Construction areas change, it seems like every few days. On going construction in the Main Bldg is replacement of tile on the floors. When I was there 3 weeks ago, they had one section screened off and were putting the tile down. Except for traffic being re-routed, you would never know work was being done. The was no noise heard during the day. As for the outside, they are painting buildings. Sago cay had the most activity. There were lifts in the back and front during the day, while they were painting and around 4 pm they were lowered for the night. The building near Big Pine keys also had the lift in front of it. All in all, it didn't impact my 7 day stay and the grounds were still beautiful. They do seem to work very quickly, so the outside painting might be finished by the time you get there. Have a great vacation.
