Hi Julie! Fantasmic! is such an awesome experience: Water effects, fireworks and of course, Mickey Mouse! You are in luck as Fantasmic! will be performed EVERY NIGHT at 8:30 during your stay, weather permitting of course! You can click on the
Calendar tab on the
Hollywood Studios page periodically before your vacation commences just to make sure that this is the case.
As for Fantasmic! meal packages, three (3) of Disney's Hollywood Studios restaurants currently offer this:
Mama Melrose's Ristorante Italiano,
The Hollywood Brown Derby, and
Hollywood and Vine. Hollywood and Vine is a buffet experience, while Mama Melrose is classified as more casual dining, and The Hollywood Brown Derby as more of a fine dining experience. Of these, I have experienced Mama Melrose and have had a fantastic meal there. It's good Italian food and a great ambiance. Should you want to book a Fantasmic! dining package, call (407) WDW-DINE up to 180 days in advance and specify your restaurant of choice.
Hope this helps you plan a magical vacation for you and your family!
