Hello Courtney!
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 up to 60 days in advance. It sounds like you made your theme park reservation for
Disneyland Park. Your reservation confirmation will state your Park Reservation Date, Selected Park and Arrival Time. At this time, your arrival window is “All Day.” This means you may enter your first theme park at any time during the theme park hours and you do not need to arrive by a certain time.
Because you have a Park Hopper ticket, you may hop to
Disney California Adventure 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 planDisney with more questions in the future!
