Hi there Kezia,
Welcome to planDisney and thank you for your question! I am thrilled to hear that you'll be visiting the Happiest Place on Earth next month - it'll be here before you know it!
From what I see on the
Hours & Events Calendar when answering your question, it looks like you're correct!
World of Color - ONE has some showtimes up through the first week of September on the off nights in between the
Oogie Boogie Bash - A Disney Halloween Party, but I do not see it on the calendar from September 9 through the end of the entertainment calendar availability at the moment.
From what I've seen, if an attraction or show is planned to be closed for refurbishment, it is not likely to change. Luckily, there is so much to see and do around the Disneyland Resort during your trip as part of the
Halloween season! Specifically, I would highly recommend
Halloween Screams in Disneyland Park - it's a must-see.
There are also some delicious seasonal food & beverage options that come with the Halloween season. Make sure to check the
Foodie Guide on the Disney Parks Blog - but I wouldn't recommend looking at it when you're hungry!
Thanks again for your question, Kezia. I hope you have a wonderful visit to the Happiest Place on Earth next month.
Have a Magical Day,
Greg
