Hey there, Alexandra! Welcome to planDisney!
It looks like a spooktacular trip to the Disneyland Resort is just around the corner for you! I hope you've carved out some time for a little
Halloween-themed magic, like
Haunted Mansion Holiday or
Mater's Graveyard Jam-BOO-ree! One of the coolest parts of the holidays at the parks is the ride overlays like these that can really jumpstart that spooky spirit!
If you have
theme park reservations for a particular day, you will not be able to enter the parks on the day before. If you'd like to change your day, you will want to take a look at the
Theme Park Reservation Availability Calendar to see if the previous day is available to reserve. If you see that it is, you can cancel your original theme park reservation and make a new one for the day you'd like to go. If the new date differs in price from your original purchase, you can pay the difference to change the reservation.
Alexandra, I apologize if I've misunderstood your question. I'd be happy to help further if you'd like to send more detailed information in the form of a new question through
planDisney! Enjoy your time at The Happiest Place on Earth!
Until we meet again,
Ashley
