We were there from Dec. 19th to the 27th last year and are returning this year from the 20th to 28th. Last year, crowds were very manageable right through Christmas Day. Christmas Eve mid-day in MK and Christmas Day afternoon in Epcot were very busy but not packed like the following week. Of course, the threat and eventual downpour of rain Christmas morning kept most people away from MK on Christmas morning -- which was absolutely wonderful!!! Dh and I agreed that attendance the week before Christmas seemed far lower than our late May, fall break (mid-Oct), and spring break (mid-March) trips!!!
