Hi, Irma!
Welcome to planDisney, and thank you for sharing your question with us!
I'm happy to share that
I can currently see availability for reservations for Disney California Adventure Park right now. So if you can see the same when you read this answer, I recommend buying your ticket and booking it as soon as possible.
If reservations are unavailable, you can
book a room at a Disneyland Resort Hotel to access their dedicated reservation inventory. This is a good strategy because the Disneyland Resort has a separate reservation pool for Guests with room reservations.
If you
see availability for Disney Hotel Guests on this calendar, the path is simple. You will book a room at a Disneyland Resort hotel, link it to your Disneyland profile, and then buy your tickets to secure your reservation. This strategy comes with a
bunch of extra perks, such as amazing pools,
early entry, and package delivery. How does that sound?
The ticket booths at the Disneyland Resort have access to the same calendars I linked above. So if both calendars don't show availability, the ticket booths won't have day-of tickets as well. But I'm confident you will be able to visit the Disneyland Resort tomorrow if you follow one of the strategies I suggested above, Irma.
I'll be crossing my fingers for you, Irma!
May the magic be with you,
Julie
