Hello there Greissi,
Welcome to planDisney and thank you for your question!
You have asked the question of the hour! Unfortunately, I also don't have the answer. There have not been any official announcements yet as to when tickets will go on sale for this year's
Oogie Boogie Bash - A Disney Halloween Party.
My suggestion would be to keep an eye on the event page, linked above, and the
Disney Parks Blog! Since the event is starting earlier this year, I would imagine that we should hear more soon about when these special event tickets will be available for purchase!
Once the details are released, I would highly recommend planning to purchase them the day that they're available. This event has been extremely popular the last few years and tickets have limited availability, so many of the days have sold out once they became available.
The event itself is so much fun! I went last year with my son and we had a great time getting to see some of our favorite villains and we got so much candy.
Thank you again for your question, Geissi. I hope you enjoy your visit to the Happiest Place on Earth later this year.
Have a Magical Day,
Greg
