Greetings, Jennette! Welcome to
planDisney.
Unfortunately, it is not possible to use another Guest's
Park Reservation that they intend to cancel. I am sorry if this is not the answer you were expecting to receive.
My recommendation to you is to regularly check the
Reservation Availability Calendar online or through the
Disneyland App. This is a live calendar that is constantly being updated. You can even check it every 10-15 minutes. Guests are always changing their plans, so you may see that a certain date that was once unavailable suddenly becomes available. However, keep in mind that there are no guarantees as reservations are subject to availability.
Jennette, although I am not sure when you are planning to visit
The Happiest Place on Earth, anytime is the best time to visit. The
Disneyland Resort's Event Calendar for 2024 was recently released for the first time, which is essential for planning future visits.
I hope this helps, Jennette. I am sending you pixie dust to help you secure a park reservation!
Your Pal,
Alejandra
