When I was there last week, we watched for the Xmas decorations. Epcot still had the tree up 1/3, but it was down 1/4. The lovely white arch, however was still up when we left 1/6. On 1/4 the tree at Y&B was still up, as well as the chocolate decorations. At BW, the chocolate carousel was still up 1/5, but gone 1/6. And the last night for the Osborne Lights was 1/2, but they were still up (unlit, of course) during the day of 1/3. I remember the light poles around the Boardwalk were still strung with garland on 1/6, but there was no more Christmas music playing. The thing I noticed aboutthat tree in Epcot was that not only had they taken it down, in true Disney fashion they had replanted the area with flowers, not just left a big bare spot, all in one night.
