For years, due to college break schedules, we always arrived at Disney sometime between New Years Day and 1/3 and stayed until between 1/7 and 1/9. Most of those years we stayed at VWL and for a few years we would go to the main WL lobby late in the evening, get a hot chocolate from Roaring Forks and just sit in the lobby and wait until after 11:00 p.m. to see if the tree and decorations were coming down that night. We witnessed the process two or three times. It always happened around the 4th or 5th of January. We always called it "the undecorating of Wilderness Lodge" An entire crew of people would show up with huge crates, boxes, etc. and begin. One of the castmembers told me everything is numbered and the crates the items are stored in are also numbered. It was pretty neat to see them drive a lift truck into the center of WL lobby to get the higher decorations and the tree down. They would work all night long and finish up at 5 or 6 in the morning...my two sons actually stayed in those comfy chairs just watching until 4:00 a.m. one year! The crew of castmembers told us that once all the crates got back to the warehouse they were all rechecked and any needed repairs made to the decorations over the next few weeks. This whole process was repeated every night, in every resort and every park until all decorations were down.....but I seem to remember everything being pretty much gone before we would leave to come home usually around the 9th.
