We have been at WDW the last 6 years for Christmas. It is VERY busy, but a lot of fun.
The parks are open late and the Christmas sprit is every where. Based on you tag line you have been a frequent visitor to WDW.
There will lots of special things to do and see. Slow down and spend time looking at all the unique things for the holidays.
The resort hotels have some wonderful displays. Make sure you have PS's or you be eating at odd hours or eating counter service.
We are throwing a large expensive party this year and will be skipping our annual Christmas trip. I am already going thru withdrawal . PM me if you have any more ??
