We go every few years at Christmas time, and love it. But the best story is about 10 years ago. I think it was the first, or possibly second, Christmas season for Grand Fla. We got there a few days after Thanksgiving. We were in one of the long buildings, don't know what they are called, not the main building. Our room was on the fourth floor, right off the atrium. Anyhow, got up the next morning, and while the kids were grabing their stuff, I walked out onto the landing outside the room. Somehow they had erected, and decorated, a four or five story Christmas tree, overnight, without a sound. We were stunned to see it, not only because it looked great, but because it just wasn't there the night before and we never heard them working on it.
Next time we went down at Christmas time, we went over to see it, however all that was there was a small, couple feet, tree. We asked someone from housekeeping if we had only imagined it. She said they only did it for a year or two and it was too much trouble or cost. But boy, when we think about Christmas at WDW, we think about that tree.
