- A FOURTH OF JULY CONCERT IN THE SKY"
Traditionally, the 4th of July fireworks at the Magic Kingdom include an enhanced presentation featuring patriotic music themed to spectacular pyrotechnics that ring through the park. This year’s schedule:
7/4/09 - 9:00PM: Holiday Fireworks
DISNEY’S HOLLYWOOD STUDIOS
Nothing had been released for 2009 for this park.
7/4/09 - 10:00PM: Illuminations with special Fourth of July finale
Nothing had been released for 2009.
***Please note these days are some of the busiest of the year. If you are visiting a theme park during this holiday, you should arrive early and expect to stay for the remainder of the day.
Historically, the parks do reach capacity and guests will no longer be able to enter once this occurs. Having a dining reservation will not get you into the park once it is closed.
If you are staying at a Disney Resort, you are guaranteed entry to a theme park, but not necessarily the one of your choosing. Again, get to the park early and plan on making a full day of it.
