Hi Elizabeth! Congratulations on your first-ever Walt Disney World Resort vacation! I am so excited for you! Since this is your first visit, I've linked a special video to your answer! This video includes some great tips for first-time visitors!
Fantasmic! is my favorite nighttime show at the Walt Disney World Resort! Taking a journey into Mickey’s imagination provides Guests with a magical visit with some of our favorite Disney characters of all time together in one show!
Reserved seating for the Fantasmic! show is only available through the Fantasmic! Dining Package. You can
purchase the Fantasmic! Dining Package on the Walt Disney World website using the link I provided in this answer. Please note that the dining package is different than simply making a reservation at the restaurant. A reservation at the restaurant does not qualify a Guest for seating at Fantasmic!
If you reserved the Fantasmic! Dining Package, you can pick up your seating voucher at the time of your meal. Your seating voucher means that you will have access to a reserved seating section. You will select your seats – first come, first served – upon arrival at the reserved seating section. Seating begins 90 minutes prior to the show. Guests should arrive at least 25 minutes prior to the show.
It sounds like you have your reservation scheduled for the
Sci-Fi Dine-In Theater Restaurant. You are going to have a great experience! There are four other restaurants available to book through the Fantasmic! Dining Package! They are the 50’s Prime Time Café, Hollywood & Vine, Mama Melrose’s Ristorante Italiano, and The Hollywood Brown Derby!
Enjoy your meal and the show! And, as Mickey says, “That’s some imagination!”
Happy Planning!
Jonathan
