Hey Michael!
A very warm welcome to planDisney and thanks so much for dropping by with a question!
Let me explain the steps to modify your
Theme Park Reservation. But first, because reservations are limited and subject to availability, I recommend checking the
Availability Calendar before you attempt to change your reservation. This will allow you to confirm your new theme park choice is accepting reservations for your ticket type on your desired dates. Once you’ve confirmed availability, you may modify your Theme Park Reservation by logging in to your
Disneyland Account and selecting "My Disneyland." Then, click "Ticket and Reservation Details" and select "Cancel Reservation." After you receive the confirmation of cancellation, you’ll be able to book a brand-new one. It’s that easy!
But, your current itinerary sounds ideal to me! I love to switch up my starting park on alternate days. And, with a
Park Hopper Ticket, you have the option to hop to the other park starting at 11 a.m. (subject to theme park capacity.) So, if I were you, I would leave everything as is. Unless you have an early dining reservation at the other park you are trying to accommodate.
I hope you return to planDisney with your questions in the future! Have a magical 3-day vacation!
