Royal Greetings, Francina!
Thanks for bringing your question our way. I'm thrilled to hear about your upcoming visit and am ready to assist.
Though you were able to secure a reservation for
Cinderella's Royal Table, separate admission for Mickey's Not-So-Scary Halloween Party is required to dine at that time.
Magic Kingdom Park closes to daytime guests at 6 p.m. on evenings when the Halloween Party is scheduled, and Cast Members will be stationed throughout the park checking for party wristbands. If you do not have a wristband you will not be allowed to enter certain areas and will not be permitted to linger to wait for your reservation. Guests will be directed toward the exit during the 1-hour window between the official closure and the start of
Mickey's Not-So-Scary Halloween Party.
If you have your heart set on dining in Cinderella Castle I recommend booking an earlier reservation that day. At the time of my writing, a few breakfast and lunch reservations were still available depending on your party size. You might also consider attending the Halloween Party for more festively spooky fun, but this will be an additional purchase. I've attended twice before and really enjoyed the specialty snacks, entertainment, attraction overlays, and
Mickey's Boo-To-You Halloween Parade. There is so much to do and see during this event, and I would advise against a long Table Service meal during the party should you plan to attend. Those magical hours tick by oh so quickly and you'll want to enjoy everything there is to experience beyond the castle walls.
I hope this clears up any confusion, Francina. Please come back and see us again with more questions.
Magic and memories,
Amy
