Hi Michelle! Thanks for bringing your question to planDisney.
Unfortunately, I can't predict whether security will be offered at the
Toy Story Parking Area for your upcoming trip. It is periodically available; often that's during peak times to visit the parks.
Halloween Time is certainly one of the most popular times to visit! But there's no way without the help of Madame Leota's crystal ball to see into the future on this one, I'm afraid. Security in the parking area could be offered some days of your visit and others not. It also may not be available for the duration of your trip.
I wish I could give you a firm answer, but I can assure you that wherever you pass through security, you'll find it impressively efficient. The lines may look lengthy at certain times of the day, but my family is always surprised by how quickly we make it through them. Being prepared on your end will certainly help. Be aware of
park rules, so that you don't have anything that isn't permitted along with you, to help speed your way through. Rules are subject to change, all persons and items may be subject to inspection, and it is up to the discretion of security as to whether something can safely be allowed in the parks.
Take a look at the
Daily Events Schedule to plan your must-do activities. Adjust the date to view each day of your visit. While schedules are subject to change or cancellation, it'll help you sketch out the fun. There should be more than a sprinkling of seasonal magic ahead of you that you won't want to miss! The Mickey and Friends Cavalcade in Disneyland Park would top my list.
I hope this helps.
Elizabeth
