Hi Kelli,
Love that you are planning ahead for
Fantasmic! Its one of my favorite performances at Disney. As you know, the Fantasmic Dinner Package includes choosing lunch or dinner at 1 of 3 restaurants:
* Hollywood Brown Derby (lunch or dinner)
* Mama Melrose's Ristorante Italiano (lunch or dinner)
* Hollywood & Vine (dinner only)
It also includes seating in a reserved section for Fantasmic! The section is reserved but the seats within the section are not & are available on a first come basis. This will cut down on your wait time but I'd still suggest arriving at least an hour prior to the performance time - the earlier you arrive the better seat selection you'll have within the reserved section. If you run into any problems, speak with a Cast Member in the reserved section for assistance.
Bring something to keep you entertained while waiting for the show - especially if you have small kids. Its worth the wait & good things come to those who wait.
Enjoy Fantasmic! Wishing you many magical memories :-) Allison
