This is our 4th Holiday season at WDW. You'll know from the crowds the days before what to expect on Christmas day. MK can and usually closes around 10am because it has reached capacity. We don't have small children to make MK a necessity and even if we did, we probably wouldn't brave it. We do like Epcot because we can stroll almost leisurely around the WS. It's crowded but so much better than MK. Don't expect to ride any rides either place unless you're there early. Several years ago I ran into MK at opening to buy some collector's pins. It's not a scene I want to repeat. And we still go every year for the Holidays! ADR's are a necessity anywhere! We do a lot of people watching on those trips and even carry books into the parks so tha we can enjoy the excitement of being there without the anxiety of being there. It's our trip of lights, fountains, decorations, music and food. Maybe when we have those little ones again we'll go to one of those quiet parks like AK or MGM on Christmas, but not on NYE!
