Hello Brittany!
A very warm welcome to planDisney! Thanks for bringing your question our way!
I’m sure you’re looking forward to your vacation to “The Happiest Place on Earth!” And, it sounds like you’ve already reviewed the new guidelines on the
Know Before You Go webpage on the Disneyland Resort website. I'm so glad that you are aware of the new requirement for making an advanced
Theme Park Reservation using the reservation system. This reservation is required in addition to your valid admission ticket and you can make a reservation for one theme park each day of your trip. Reservations are currently being accepted through June 2021.
If you would like to modify your reservation, please log in to your Disneyland Account and visit My Disneyland then click Theme Park Reservation Details. From there you may cancel your reservation. You will then be able to book a new theme park reservation. Reservations are limited and subject to availability. As you mentioned, I do recommend checking to make sure the theme park where you would like to start your visit has availability on your desired day. To do this simply visit the
Availability Calendar on the Disneyland Resort website. Since you have a Park Hopper ticket, you may hop to another park after 1:00 p.m. on the day of your visit. You are not required to make an additional theme park reservation to visit a second park. But, as always, theme park admission is subject to attendance availability.
I hope this helps! Please come back to see us here at planDisney!
