Hi McKenna, welcome to planDisney!
Thanks for bringing your question to us, I'm happy to help you troubleshoot!
So first and foremost, I checked the
Theme Park Reservation Availability Calendar, and I see availability for both 1 Park Per day Tickets and Park Hopper Tickets at only
Disneyland Park for October 15, 2022. So if you're trying to book a reservation for
Disney California Adventure Park, that might be why you're unable to. If you have a Park Hopper Ticket, a workaround would be to book a
theme park reservation for Disneyland Park, and then to "hop" over to Disney California Adventure Park after 1:00 p.m.
Another reason why you might be unable to book a reservation for October 15, 2022, is due to the Tier of your ticket. The
Disneyland Resort uses a
ticketing tier system for
standard one-day theme park tickets. This means the price of the ticket will vary depending on the theme park reservation date that you select. Tickets currently range from Tier 1 to Tier 6. Tier 1 has the most restrictions in terms of eligible reservation dates and Tier 6 has the least number of restrictions. The ticket that you purchase will be valid for admission on the date you selected and on dates in the same or lower tier. Peak demand days, like holidays and weekends, are typically higher tier days. October 15, 2022, is on a weekend, so if you had originally purchased a standard one-day theme park ticket for a weekday, that would be the reason you are unable to book. If that is the case, you can call the
Disneyland Resort Ticket Line at 714-781-4636, and the Cast Members can help you upgrade your ticket! Also just so you know, the ticketing tier system does not apply to multi-day tickets.
Last but not least, I would double-check to ensure you do not have a current reservation already booked. If so, you'll need to cancel your current theme park reservation, and book a new one for October 15, 2022! You can check by logging in to your Disneyland Resort account, selecting the "My Disneyland" link, and then clicking the "Ticket and Reservation Details" link.
