It isn't there for nearly as long as everyone seems to think. They put up the lights, remove the cranes and bring them back to take them down again. I only remember one extended stay in the spring when the did some major repair work the castle. I, for one, am happy about having that reaction because that is one of the main reasons why they don't do overlays in WDW. People barely tolerate having things down for a brief time. Can you imagine what would happen if the shut down HM for around six month a year to do the holiday overlay. There'd be a revolution. We have to remember that those thousands of lights do not put themselves up especially when we considerate "Guest" insisted that they only be put up eight hours of every day in the dark. Maybe if we were to be just a little more tolerant it would be done a lot quicker, but, for a brief time our magic bubble would be popped.
