Following final Mickey's Very Merry Christmas Party, Holiday Wishes, Mickey's Once Upon a Christmastime Parade, and Celebrate the Season all play during regular park hours for all guests. They all begin on December 21 2013, with two parade performances at 12:30pm and 3:30pm, with Holiday Wishes at 10pm. Of course, if you want to see these earlier, they are all part of Mickey's Very Merry Christmas Party which begins on November 8 2013.
Note: During the party nights, Holiday Wishes features 180 degree perimeter fireworks that are not part of the show once it begins to perform during regular hours.
