Hey Howdy Hey Chaeyoung and welcome to planDisney!
Mickey's Not-So-Scarry Halloween Party is such a fun event. There are so many unique experiences, treats and opportunities during this party and I am so excited to hear you have your tickets purchased as this is a very popular event! In case you need an extra ticket on a date that is sold out, let's go over what options you may have.
In some cases, Disney may adjust the number of party attendees and open new ticket sales. While this move is rare, it has happened in the past. I would keep checking to see if there are any new ticket options. You can always check on the day of the party as well. This is another very rare instance of last-minute availability but it never hurts to ask!
While I'm sure you have your plans for the party coming together with all your must-dos ready to go, I wanted to throw in a recommendation for you to check out
Mickey's Boo-To-You Halloween Parade. This parade is super fun and you get to see so many characters you would not normally and so many familiar ones dressed up in their Halloween costumes. The music is great and the energy really ramps up to continue throughout the night. Don't forget to do a little trick-or-treating as you make your way throughout the park as well!
Chaeyoung, I hope some Magic comes your way to add another to your party. If you have any other questions don't hesitate to let us know, we are always happy to help!
Boo To You,
Nick
