Hi there, Karen!
The answer to both of these queries is
yes. You
can bring food into the Parks, and you
are permitted to eat in the
Fantasmic! amphitheater.
Because this is such a popular show, you should plan to
queue up at least an hour before doors open, typically two hours prior to the first show of the night. And you can be the judge: if the crowds look particularly large on your travel day, you might want to send a "placeholder" to queue up even earlier than that.
Concession stands are located at the back of the theater. Many Guests do choose to purchase food from the stands and eat in their show seats.
Several restaurants (currently Hollywood Brown Derby, Mama Melrose's Ristorante Italiano and Hollywood & Vine) offer a
Fantasmic! Dinner Package; there is a credit card guarantee to hold your spot, but no additional charge.
The package entitles the diner to guaranteed seating at a night's Fantasmic! performances.
This plan is excellent if you don't like to wait for a show, or if you are traveling with children who get antsy during long waits. You can make your reservation by calling (407) WDW-DINE or by
booking online.
Have a great time!
See you later, celebrator,
