Hey there Elizabeth,
Welcome to planDisney and thank you for your question! This does seem to be the question of the hour!
I'm anxiously awaiting an announcement as to when ticket sales will begin for this year's
Oogie Boogie Bash - A Disney Halloween Party, so you're in good company! So far, this hasn't been any official announcement, but there was an
article that covered the dates and some of the details for this special event.
I would recommend keeping an eye on the
special event page and the
Disney Parks Blog. These would be the two places that I would expect to see updates as soon as they are available. Since Oogie Boogie Bash - A Disney Halloween Party starts a few weeks earlier this year, we should hear more soon.
As soon as the purchase dates have been announced, I would also highly recommend planning on trying to buy your tickets as soon as they're available. They are subject to availability and have sold out the last couple of years.
I was able to attend this special event last year with my son for the first time, and we had a blast! Again, we should hear more soon so keep an eye on the Disney Parks Blog. Thanks again for your question, Elizabeth!
Have a Magical Day,
Greg
