I forget where I found calendars for last year, but I did, maybe Touring Plans.com? Either way, I bought a membership there for $14.99 for the year. It provides estimated park times and EMH based on previous years calculations. Of course everything can change up to the week you go. It's SO hard to decide which day to go to which park, but you got to go with what fits with what you want to do.
Are you going to the Christmas party,
MVMCP? I heard MK days are less crowded on those days. Here's the list of dates when the party's are.
