We went to WDW Dec. 13 - Dec. 27 2003. It was absolutely magical. Echoing previous comments, the parks were extremely quiet until December 20th. That date, when we returned to our hotel (A.S.M.) there was a really long queue at Guest Services for check-in, and my thoughts were "uh-oh!" :lol:
From then on it was busy busy busy. Luckily enough, we had covered every attraction we had wanted to experience.
Back onto the subject of Christmas though, I cannot speak highly enough about the WDW Christmas experience. Walking down Main Street on Christmas Day, I started to cry, as it had been my life long dream to be in Magic Kingdom on Christmas Day, and I never thought it would come true.
Did I mention we're going back to WDW this year? (Dec. 10 - Dec. 22). We're booked in for MVMCP for Dec. 13th, and Candlelight for Dec. 15th. It'll be my first trip with a camcorder, so I'm very excited about that
The only downside for me was the weather in the evening. We really felt the cold waiting for parades/shows to start. I (mistakenly) wore my shorts on the first day. For some reason, cast members kept asking us if we were from Canada :lol: However, we were told by various individuals that the weather was colder than usual, so I'm hoping it'll be warmer this time!
To summarise, you have to go WDW at least once in your lifetime at Christmas. Pack a lot of hankies though, as many of the sights will reduce you to tears (and I mean that in a good way!)
