Hi Stacey,
Disney usually posts their online calendars 6 months in advance. Right now the calendars are up through February 2012. I would anticipate the March 2012 calendars posted around the beginning of September.
To keep an eye on the online calendars, click on these links:
Magic Kingdom
Disney's Hollywood Studios
Disney's Animal Kingdom
Epcot
Select your month of travel from the drop down list next to the
View Month tab. That will show the park hours for each day during that month. Then click on a specific day for parade & fireworks schedules. Be sure to pick up a
Times Guide available at the entrance of the parks, Guest Relations and most merchandise locations to confirm the times as schedules are always subject to change without notice.
On evenings when Fantasmic! is presented more than once, the
Fantasmic! Dining Package priority seating is available for the first showtime only.
Wishing you minnie magical memories :-) Allison
