In building 2 (and I assume the same will be true elsewhere) they worked from the top floor down, so when they brought guests back to an unfinished building there was no work above their heads--the main noisy thing would be flooring work, so that makes sense. There was work happening for our whole stay and it didn't disturb us at all. In fact, it meant there were fewer guests in our building which probably made it quieter over all. There were some construction barriers up blocking a few paths, but not the ones we needed to get to the elevator/stairs, and there was cardoboard up in the elevator, but that was it.
The second floor of building two looked ready for guests to me, but they hadn't reopened it when we left this morning. There was a flurry of work there yesterday and then today all the work I could see was on the 1st floor.
