Howdy Felipe!
I love it when a fellow Texan stops by with a question for us. Welcome to planDisney!
Your trip is right around the corner, and I bet you’re as excited as can be! Whether you’re exploring the planet of Batuu in Star Wars: Galaxy’s Edge at
Disney’s Hollywood Studios, strolling along
Magic Kingdom Park’s Main Street, U.S.A., trying delectable delights around the World Showcase at
EPCOT, or taking in the scenic views of Pandora - The World of Avatar in
Disney’s Animal Kingdom Park, you’re sure to have the most magical time!
Felipe, since the
Theme Park tickets are valid for all the parks now, you must be referring to the
Disney Park Pass reservations you’ve made, as those are now required to enter the Theme Parks, along with valid admission.
Before I get into changing your Disney Park Pass reservations, I urge you to check the
Theme Park Availability Calendar to be sure the Theme Park you’d like to change your reservation to is available. Theme Park reservations have been quite popular during the week you plan on coming and I wouldn't want you to cancel a Disney Park Pass reservation without checking for availability first. In order to change your Disney Park Pass reservation, you would have to cancel the current selection and then book the new Disney Park Pass reservation for that day.
One thing is for sure, a day spent at any of the Theme Parks is a day spent in absolute magic and delight.
Have an enchanting time, Felipe!
