Hey, howdy, hey, Karl! Thanks for swinging by planDisney with your question. We love helping Guests like you through our experiences.
The first step is purchasing the ticket, next you make the reservation. So, you wouldn’t add a ticket to a reservation, rather, you would purchase an additional ticket and then make a reservation for that ticket/Guest.
On the
Disneyland Resort website, go to “Parks & Tickets” and select “
Theme Park Tickets.” Here you will select the number of days, number of tickets, and type of ticket (One Park Per Day or Park Hopper.) Once you make these selections, you will click “Choose Your Dates” and be taken to the theme park reservation page. I am currently seeing your desired date of April 12 available, but availability can change quickly, hence I suggest securing your ticket and reservation quickly!
I hope this information is helpful, Karl. There is magic, adventure and of course Disney snacks waiting for you!
