Hello, Nicole! Welcome to planDisney and thanks for your question!
Did you purchase your tickets on the
Disneyland Resort website or the Disneyland app? If so, then you likely made your theme park reservation when you purchased your tickets. If you selected the date you wanted to visit and which park you wanted to visit before you checked out, that was your theme park reservation. No further action would be required. You can double check your tickets and reservations by clicking the "Ticket and Reservation Details" link under the "My Disneyland" menu on the Disneyland Resort website.
If you purchased your tickets from a third-party vendor, then you may still need to make a
theme park reservation. The first step is linking the tickets to your account either online or through the app. After you link your tickets, you should be able to make theme park reservations. Currently, however, it does appear that January 8th doesn't have any availability for one park per day tickets. This could change, though. Guests change plans and cancel reservations frequently and sometimes additional availability is added over time. So keep checking back for that date.
I hope this helps. Have a magical day!
