Hi there, Holly! Welcome to planDisney.
Cinderella's Royal Table is one of the most popular restaurants in all of Walt Disney World Resort, and consequently, it can be one of the hardest reservations to come by. I understand and appreciate your perseverance in trying to secure a reservation!
On Friday, October 21 Cinderella's Royal Table is open for day Guests until 5:55 pm. From 6:00 pm until 9:00 pm, Cinderella's Royal Table offers Mickey's Not-So-Scary Halloween Party Dining. If your reservation confirmation states "MNSSHP - Cinderella's Royal Table Dinner", then you have reserved Halloween Party Dining. As stated on the webpage for Mickey's Not-So-Scary Halloween Party Dining:
"Please note: You must have a ticket to Mickey's Not-So-Scary Halloween Party in order to dine in Magic Kingdom park during this event. No exceptions will be made."
Unfortunately, if you do not have tickets to Mickey's Not-So-Scary Halloween Party, you will not be able to keep your reservation. I know this is not what you were hoping to hear. I would encourage you to continue to check for available dining reservations in the days leading up to your trip. Other Guests' plans change all the time, and you might find availability for Cinderella's Royal Table during regular park hours, especially the day or two prior to your visit as other Guests cancel their reservation to avoid the cancellation penalty. I have even seen same-day reservations for Cinderella's Royal Table pop up from time to time. You can also check to see if the Walk-Up Waitlist is available on the day of your visit. Use the "plus" button on the My Disney Experience mobile app to "Check Dining Availability" and choose "Now" to see which locations are currently offering a Walk-Up Waitlist.
Cinderella's Royal Table and Be Our Guest Restaurant are the designated locations for Mickey's Not-So-Scary Halloween Party Dining from 6:00 to 9:00 pm. Other Magic Kingdom Park table-service dining locations, including The Crystal Palace, Jungle Navigation Co. LTD Skipper Canteen, and The Plaza Restaurant are open for reservations for all Guests until 6:55 pm. Guests without a party ticket who finish their meals after the party has begun will be ushered to the front of the park after enjoying their meal.
Holly, if you have any additional questions, please feel free to stop by planDisney again anytime. We are always happy to help.
