Hello Zachary and welcome to the Disney Parks Moms Panel where it's a pleasure to assist you in planning towards your upcoming magical visit to Walt Disney World Resort.
You've already made a super smart choice by opting to utilise the wonderful and awesomely time saving
Dining Event Packages for nighttime shows such as the
Fantasmic! Dining Package and I'm happy to share that Guests may indeed use their
Disney Dining Plan credits in those participating restaurants where required and you'll be pleased to know that currently Dining Packages do not incur the use of
extra credits;
For example if using the Fantasmic! Dining Package for
Mama Melrose's Ristorante Italiano it would incur 1 x Table Service Credit per person or for the
Signature Dining location
The Hollywood Brown Derby it would incur 2 x Table Service Credits per person - but incurs
no extra credits for the use of the Dining Package!
If I can help sprinkle any extra pixie dust onto your upcoming Disney plans, please do pop back to ask me another question.
Have a great Disney day.
~ Jane
