Hi Tanya! Thanks for dropping by planDisney.
It sounds like your plans are in place and you're looking forward to a fantastic holiday at
Disneyland Resort. As you've already discovered, with a valid
admission ticket, you can always adjust or change your theme park reservation. However, park reservations are limited and can sell out for parks and dates, so please be aware there's no guarantee of availability for a new preferred date. You will need to have a theme park reservation for each day of your visit. You'll need to secure them for the other days too, not just your starting date. Once you do that, you should be good to go!
You'll be visiting at one of my favorite times of the year:
Halloween time. You can expect festive décor, merchandise, treats, entertainment, and more! One of my must-dos for the season is the Haunted Mansion Holiday overlay. If you'd like to start planning your spooky to-do list, follow the
Disney Parks Blog and
Disney Eats for updates on what you can expect during your holiday.
Have a hauntingly good time!
Elizabeth
