Hi there, Anna!
Welcome to planDisney, it's great to have you here! Being able to enjoy both Disneyland Park and Disney California Adventure Park on the same day is awesome, I don't blame you for wanting to upgrade your park tickets.
You can upgrade
valid theme park tickets while you're at the Disneyland Resort by visiting the main entrance ticket booths. The new ticket you choose must be of equal or greater value to the original ticket you purchased, and the cost to upgrade will simply be the difference between the cost of your original ticket and the current cost of the new ticket you select. There are no discounts for using a specific credit card, however, I know that your Disney Visa Card will give you more rewards points for making a Disney purchase!
Upgrading your theme park tickets does cause your current theme park ticket reservations to be canceled, so you may want to upgrade your tickets before your visit and make new park reservations. You can call the
"Tickets" phone number to upgrade your tickets over the phone. Don't forget to check the
Theme Park Reservation Availability Calendar first, to make sure new reservations are available! Once you've upgraded you'll want to make new park reservations right away.
You might not get a discount on park tickets with your Disney Visa Card, but there are some other fun opportunities for cardholders! For example, there are sometimes
exclusive photo opportunities for cardholders. This is how I met Darth Vader in Tomorrowland, which was quite the experience! As a bonus, the digital downloads of these photos are complimentary in the Disneyland Mobile App. Characters and availability can vary, so it's a good idea to check the Disney Rewards website for current offerings. You will also be eligible for discounts on select merchandise purchases and dining!
Anna, I noticed that you'll be visiting during
Halloween Time at the Disneyland Resort. That is the perfect time to have
Park Hopper tickets because Disney California Adventure Park will close early some evenings for the after-hours Halloween party. But you won't need to worry, because you'll just head over for a magical evening in Disneyland Park! Enjoy all the spooky tricks and treats!
Keep moving forward!
