Hi there Dominica! I am so excited to hear that you'll be traveling all the way to California this Fall to check out Disneyland! You guys are going to have an absolute blast and Halloweentime is such a fun time to visit!
You can definitely manage to get a good feel for the parks in 2 days, but I recommend at least 3 if you can arrange it. If you only have two days, I suggest purchasing "Park Hopper" tickets which will grant you the freedom to bounce back and forth between the parks as you wish! You could visit Disneyland Park in the morning and then hop on over to California Adventure for the afternoon and evening! Cars Land is such a site to see at nighttime when all of the neon lights are aglow!
Since your traveling in October, you'll get to witness
Halloweentime at the Disneyland Resort! The parks will be decorated with orange and black and spooky touches and two popular Disneyland attractions, Haunted Mansion and Space Mountain will be transformed with spooky layovers. You can even purchase tickets to
Mickey's Halloween Party which takes place in Disneyland on select nights. If you aren't used celebrating Halloween, this will be such a fun experience! Imagine trick or treating for candy all over the park! The characters will be wearing their costumes and there will be special parades, entertainment and fireworks throughout the course of the party! Guests of ALL ages are encouraged to dress up for this fun evening event!
Best Wishes,
Amanda F.
