Hi there, Julie!
Thanks for bringing your great question to the Disney Parks Moms Panel. I can't wait for you to enjoy fall and
Halloween Time at the Disneyland Resort this September. For the evening of
September 13, 2018 Disney California Adventure Park is closed for a private event after 5 PM. I'm sorry if this interferes with any of your trip plans, but I'm glad you are preparing now so that you can make the most out of this evening in Disneyland Park, the Downtown Disney District, or at your
Disneyland Resort Hotel.
If you weren't planning on visiting Disneyland Park this evening, this may be a great opportunity to make a fun and delicious
dining reservation, enjoy your Disneyland Resort Hotel's pool and amenities, or explore the entertainment of the Downtown Disney District like the new Splitsville location or
Star Wars: Secrets of the Empire.
Keep in mind that Disneyland Park and Disney California Adventure Park will return to their normal operating schedules the following day, September 14, 2018.
I hope this information helps, and please return if you need any extra help planning your magical trip.
-Jennifer
