Hello Berenice,
Thanks for coming to see us here at planDisney!
I'm happy for you and your Mouseketeers that you're planning to enjoy
Disney California Adventure Park.
It's sounds like one more of your Mouseketeers would like to join you, and while you're checking for reservation availability, you're not seeing that your desired date is available. I can understand that's disappointing.
Berenice, the one suggestion I can offer, and I'd love to have a more spectacular suggestion to share, is simply to keep checking the
Theme Park Reservation Availability calendar. It is possible for theme park reservations to become available for selection on a rolling basis. You can check the
Theme Park Tickets & Reservations system online, or use the
Disneyland Resort mobile app to access the Ticket and Reservation Details feature from the app's home screen.
I'll also mention that you can use the
My Theme Park Reservations features to manage your reservations should you need to cancel a reservation so that you can make a new one for a different date based on availability.
Berenice, here's hoping that all of your Mouseketeers get to enjoy the magic of the Disneyland Resort theme parks together as you'd like.
And here's wishing you lots of Disney magic in your day today!
Jerry
