Hello Susan, and thank you for bringing your question to planDisney! How exciting that you'll be visiting the
Disneyland Resort during the Fall, it's one of my favorite times to visit!
You are ahead of the game Susan which is great! However, you will not be able to book
theme park reservations until 120 days out from your trip, which would be around June 19. I would mark the date down in your calendar to secure all of your theme park reservations then!
In the meantime, I recommend exploring dining options for your family, you'll be able to make
dining reservations up to 60 days in advance. I'd also explore
Disney Genie+ service if riding attractions is important for your family, it can truly help save valuable time during your park days, I highly recommend it! Since you will be here during Halloween time, I'd also make sure to get a family photo with all of the festive fall decorations to commemorate your trip!
Please do not hesitate to bring any other questions back here to planDisney Susan, we're here to help!
Have a magical day!
Melissa
