We were there November 15-18 last year. Osborne Lights at DHS had been going for about a week, some decorations were up on Main St. in MK, but not the tree. The icicle castle lighting was active. Epcot and DHS trees were up and decorated...can't remember AK, but I want to say yes. We stayed in Wilderness Lodge. When we arrived, no tree, but on our last morning we opened the door and it was up and decorated. Also, the gingerbread house at the Grand Floridian was up.
