Hi Nicola,
Thank you for sending your question to the Disney Parks Moms Panel. Scheduling Advanced Dining Reservations and planning the fine details are almost as fun as actually being at Walt Disney World Resort. I look over my plans almost daily, to make sure I am happy with our itinerary prior to arriving at Walt Disney World Resort.
Looking at the
schedule for Happily Ever After, it seems as if they are scheduled to begin at 7:55 most nights of your visit. Unfortunately, you will not have enough time to finish your dinner at The Crystal Palace in time to catch the Fireworks Spectacular on that night. I would recommend planning to watch Happily Ever After on another evening, or if possible, modify your Advanced Dining Reservation for an earlier or later time. To do this, login to My Disney Experience and click on the "My Reservations and Tickets" tab. From there, scroll down to Dining Reservations and beside your Crystal Palace Reservation there will be the option to change reservation. Click on that option and follow the prompts on your screen. Hopefully there will be a better time so that you can enjoy both dinner at the Crystal Palace and Happily Ever After.
I hope you have a magical time at Walt Disney World Resort, Nicola. Please let us know of you have any other questions, we are always happy to help.
Stephanie
