Hi Veronica!
Welcome to
planDisney! We are so happy you're here. How exciting that you are making your way to the Happiest Place on Earth VERY soon!
It sounds like you have
theme park tickets all set to go and a
theme park reservation for
Disneyland Park. I'm so happy to hear that you are all set with both as they are both required for entry. As you have discovered, theme park reservations are subject to availability. I just took a peek at the
theme park reservation calendar and see that there are currently no additional reservations available for
Disney California Adventure Park. We do recommend continuing to check the calendar, especially the day before your visit. Guests are constantly modifying their plans and reservations can (and often do!) open up! My recommendation is not to make any changes to your current reservations until you see that there is availability at Disney California Adventure Park. At that point, you can easily go into your "Future Plans" section on your Disneyland Mobile App, click on the day you wish to change and you will see the option to cancel your reservation for Disneyland Park. Then you will need to rebook the reservation for Disney California Adventure Park. Another option would be to head to the ticket booths on the Esplanade when you arrive and inquire if an upgrade to a Park Hopper ticket is available for that day. While this is not a guarantee, if it is available, this would allow you to hop between parks after 1 p.m. and you'll be able to race through
Radiator Springs Racers, embrace your inner Peter Parker on
WEB SLINGERS: An Amazing Spider-man Adventure and chase down Jack-Jack on the
Incredicoaster!
If you are unable to change your reservation before your trip, I do have some very jolly news for you! You will be able to catch the very last few glimpses of festive cheer, including my personal favorites
Haunted Mansion Holiday and
"Believe ... In the Holiday Magic" Fireworks Spectacular! You may even catch a magical snow flurry!
Veronica, I truly hope your upcoming vacation is filled with some pixie-dusted magic! If you have any other questions, planDisney is here for you!
Keep wishing on those stars,
Tara
