I am taking my daughter and her friends to NYC for the day on 12/6. I know the tree lighting is on 12/3 so the Rockefeller Center will be fully decorated. When do the stores, Macy's, Bloomies, Barney's, etc. reveal their Holiday window displays? I can't find any dates on line and just hope they are up when we are there. We are planning to do the window walking tour. Thanks!
