We will be at WDW next Christmas (December 21st -28th, 2013). We have always taken advantage of the morning extra magic hours to beat the crowds. They have definitely helped us during the busy times. What kind of effect do the evening extra magic hours (12:00 a.m-3:00 a.m) have on crowd levels? I would think being that late, it would eliminate all people with young kids. Is it significant enough to give a try? Obviously staying up past 3:00 a.m. would eliminate any chance of hitting an extra magic morning the next day. Maybe a combination of the two during our trip would be worth a try. We know that we can't do everything during this crazy busy time, but we are looking for the best approach.
