Hi Cara.
It's always a little bit tricky to guess what Extra Magic Hours are going to be far, far in advance.
Definitely, looking at this year's Park Hours for December will give you a pretty good indication of what to expect in terms of regular operating hours for next December.
Extra Magic Hours can depend on guest volumes and even special groups visiting the Walt Disney World Resort. Looking at December 2012's Extra Magic Hours will give you an
approximate idea of the frequency of EMH for next year at each of the parks. When predicting next year's EMH schedule, you may find that the day of the
week, rather than the 'date' is the more likely consistent
factor. I've even been in the parks when they've made an announcement that the park is staying open an extra hour or two when it wasn't posted in advance! That's a fun sort of magical, last-minute surprise!
In late June and early July of 2013, be sure to visit the
Park Hours and Updates page of the Walt Disney World website as the information should be posted around that time. Since you won't be reserving your Dining Reservations until then, it works out well. I often make last-minute changes to our itinerary and dining based on park hours and additional Extra Magic Hours!
Thanks for visiting the Moms Panel with your question Cara.
I hope you'll write me back again soon!
Wishing you a simply Magical time as you begin planning your Walt Disney World vacation!
