I did Christmas in 2012, I remember trying to book by our guest on Christmas Day and not getting anywhere. On the day magic kingdom was so full I managed to get a walk up to be our guest. As for New Year’s Eve I remember there was a 5 hour wait for soarin. I am going back to Disney after cruising for a few years in October. And due to the new transport system was planning to go back next October. As I work weird shifts I have to work out the work calendar and when I did it for next year the way it falls I can go back at Christmas again.
