The decorations are usually down in the parks prior to the start of marathon weekend. That's the first full weekend in January (Jan 6, 7, 8 2006). The resort take then down after the parks. We were at WL in Jan 04. The decorations were taken down on that Sunday night during the night. We got up on Monday morning and they were gone. The lights of winter at Epcot were still up for the Marathon, but they only turned them on for the marathon, not for the evenings at Epcot.
