Hi there Oscar,
Thank you for reaching out to us here at planDisney with your question, we are so happy you took the time to visit! It looks like you are planning a visit to Walt Disney World Resort later this year, how exciting! I love visiting Walt Disney World Resort during the fall, the décor is absolutely beautiful, and who doesn't love the spooky theme of
Disney After Hours Boo Bash!
Currently, guests are not able to modify
Theme Park Reservations, however you are able to cancel your existing Theme Park Reservation and then book a new one. This process can be done in
My Disney Experience, under "My Plans" and then "Park Reservations". Once you have verified that the Theme Park you would like to visit is still available, simply cancel your reservation and then make a new one. I do recommend switching your reservations as soon as possible to ensure there is still availability at your preferred Theme Park.
I hope you have a magical time at Walt Disney World Resort, Oscar. If you have any other questions, please don't hesitate to come back to
planDisney, we are always glad to help.
~Stephanie
