Hi Mandy, welcome to planDisney!
I just checked the
Theme Park Reservation Availability Calendar, and currently, only
Disneyland Park has reservations available on June 9, 2022, for
one park per day tickets. Reservations for
Disney California Adventure Park are all booked for one park per day tickets. However, I see that park hopper tickets still have availability for both parks.
So you have two options available. You can purchase the one park per day ticket and book a reservation for Disneyland Park for the time being. Then keep an eye on the reservation availability calendar, as reservations are fluid and constantly changing. If you see a reservation for Disney California Adventure Park open up, you can cancel your current Disneyland Park reservation, and go book a new one!
The second option is to purchase a park hopper ticket and set Disney California Adventure Park as your starting park. That way you will secure your visit to Disney California Adventure Park, and also give yourself flexibility in case you want to hop over to Disneyland Park.
Plus the Disneyland Resort is bringing back its nighttime spectaculars on April 22, 2022, with the
Main Street Electrical Parade and
Disneyland Forever fireworks returning to Disneyland Park, and
World of Color returning to Disney California Adventure Park! So it could be worth it to have a park hopper if you want to catch the nighttime experiences at both parks!
See ya real soon!
