Hi Kevin and welcome to planDisney!
How exciting that your Walt Disney World vacation is in just a few weeks! You're already off to a great start with
Mickey's Not-So-Scary Halloween Party, which is one of my favorite special events at Walt Disney World.
It's been awhile since I've done a dessert party during Mickey's Not-So-Scary Halloween Party, but I recently attended the
Magic Kingdom Fireworks Dessert Parties: Seats & Sweets on a non-party night and also during
Mickey's Very Merry Christmas Party last year. You can check-in for
Disney's Not-So-Spooky Spectacular Dessert Party at Tomorrowland Terrace one hour prior to the fireworks, which looks to be at 10:15 PM on party nights, so I would plan to be there around 9:00-9:10 PM if you want to get there early. You can arrive at any time after 9:15 PM though, so if you want to enjoy the attractions and festivities a little longer, that's no problem. The desserts are replenished all night long until the very last minute, so there's no need to worry that they will run out. The better seats are towards the front, so if you have a seating preference, I suggest getting there early. Make sure you come with an appetite! You're going to want to try at least one of everything and make sure you take pictures! One of the things I was excited to see return to the party is POG (passion, orange, guava) juice. It's my favorite, so I always love to see it offered at various restaurants and parties.
I do hope you enjoy your No-So-Spooky Spectacular Dessert Party next month. Please stop back by and visit if you have any additional vacation planning questions.
Have a magical day!
