Hi, Geraldine! Anyone is eligible for the Fantasmic! dinner package, you just have to book the package.
There are a limited number of packages, and they are very popular, so I encourage you as soon as you know your dates and are within 180 days of your travel, contact 407-939-3463. There are three restaurants that participate in the package program - Mama Melrose; the Hollywood Brown Derby; and Hollywood and Vine. There are lunch packages available as well.
The package gives you priority seating at the show, so you don't have to line up quite as early as guests without dinner packages. You will have to give a credit card to guarantee your reservation, and if you don't cancel at least 48 hours prior to your meal, your card will be charged a fee of $10 per person.
Have a wonderful vacation!
