Hi Glasy! Welcome to planDisney.
It's always a little disappointing when something you've so desperately wanted to do is sold out. Let's see if we can figure out some options for you.
If you are referring to a special event like
Mickey's Not So Scary Halloween Party, when tickets are sold out, no more tickets are usually sold. On very rare occasions, if more tickets are made available, you can check at the ticket windows outside of
Magic Kingdom Park. I would recommend doing this as early as possible because this is rare and extra tickets are probably very limited. If you are indeed looking for tickets to this specific event, I did check the calendar and at the time of my writing this answer (subject to change),
there are still tickets available to the October 13, 2023 party, which is when you have indicated you are arriving at the resort.
Always keep in mind that if you are unable to get tickets to Mickey's Not So Scary Halloween Party, there are some great alternatives. While it may not be the same, Halloween fun can be found all around the resort. Magic Kingdom Park is decorated for the season during the day too! And while party-exclusive merchandise and treats won't be available during the day, there are still plenty of
fall treats and Halloween
merchandise around the parks. You can also see if there's availability for
lunch or dinner at
Hollywood & Vine in
Disney's Hollywood Studios during your trip. This seasonal dining option during this time of year is Halloween-centric with the characters dressed in their autumn finest! Also, if you're staying at one of the resorts that has viewing areas of the fireworks, you'll be able to see many of the fireworks from
Disney's Not-So-Spooky Spectacular. And if you're not staying at one of these resorts, you can make an
advanced dining reservation for dinner at one of their restaurants and stay to enjoy the view of the fireworks! A favorite of mine is always
California Grill at
Disney's Contemporary Resort!
If you are referring to
standard theme park tickets or
Theme Park Reservations (required for all Guests until January 9, 2024) that are not available, the key is to check back at all different times leading up to your vacation. People's plans change and when they do, options are usually opened up for others to book.
Glasy, if you have any other questions, or if I didn't fully answer your question,
please feel free to reach out again and I'd be happy to help!
Boo to you,
Matt
