Boo to You, Gretchen!
Thanks for visiting the Disney Parks Moms Panel with your question. You are going to have the most frightfully fun trip to the Happiest Place on Earth this year for
Halloween Time.
As you mentioned, the
Oogie Boogie Bash - A Disney Halloween Party has sold out for the season unfortunately. While it never hurts to check for tickets the day of the event, I have been told that it is most likely not possible to find any other tickets for this party. Also there was not any special military discounted rate for this party ticket offered this year. Even if you do not attend the party, there are SO many spooktacular experiences in the parks this fall. You can ride Haunted Mansion Holiday, see the Halloween Screams nighttime spectacular, and eat an array of ghoulishly delightful treats. Plus you can still meet many of your favorite Characters dressed in their Halloween costumes throughout both parks during the day.
Active Duty and retired members of the U.S. military are more than welcome to purchase
specially priced 3-Day and 4-Day Park Hopper Tickets at their local military base, though! These tickets are deeply discounted compared to standard park tickets, and my family has been so thankful for this generous offer year after year.
I hope this helps, and please feel free to return if you have any other vacation-planning questions!
