Hiya, Morgan!
Welcome to planDisney, friend! It sounds as if you have a very spooktacular adventure coming up this summer. I cannot think of a more fabulous place for your cousin to say yes! I truly hope it is a dream come true moment for everyone! Once the question has been asked, and you are ready to start the celebration, be sure to pick up
Just Engaged buttons at any
Guest Relations location in the park. This will help let Cast Members know that you are celebrating something truly special during your visit. You can even have a member of your travel party pick the buttons up ahead of time in the parks (or from your Disney Resort hotel front desk) so that you can give them to the happy couple immediately following the proposal.
I did some checking and
Cinderella's Royal Table is
scheduled to close before Mickey's Not-So-Scary Halloween party for all the published dates in August. Restaurant and theme park hours are published 60 days in advance, so the 8/30 date has not officially been published at this time. But if this specific day follows the current time trends, it will not be available during the party. I recommend checking the restaurant hours once the 60-day mark arrives, just in case the hours are different than the previous weeks. *
A quick note regarding your question: You mentioned a 7/30 date for the party, but Mickey's Not-So-Scary Halloween Party does not occur this evening. I took the liberty of presuming you meant 8/30 as there is a special event this evening. If you did mean 7/30, please note there is not a Halloween party this night, and Cinderella's Royal Table will close at 9:05 PM.
Mickey's Not-So-Scary Halloween Party offers some incredible
Disney PhotoPass opportunities. There are Magic Shots with supernatural surprises and character experiences with fun-themed backdrops. These would make fabulous and unique engagement photos! Photos featuring your favorite character pals in their best costumes and the newly engaged couple are sure to be more than memorable!
I hope this evening is frightfully fun for everyone!
We'll see ya real soon!
Tammy
