Hi Mia, welcome to planDisney!
My family and I are huge fans of the park hopper
theme park tickets! We love the flexibility they offer, and almost always go for this option! But back to your question, you should be able to upgrade your current one park per day tickets to park hopper tickets. I see that you're located in California, so if you're able to, I recommend visiting the
Disneyland Resort Main Entrance Ticket Booths, and chat with the amazing Cast Members and they should be able to help you out! Let them know that you have
theme park reservations for September 17, 2022, and September 18, 2022. If visiting the Ticket Booths is going to be tough, you can also try calling the
Disneyland Resort Ticket Line at 714-781-4636 and see if the Cast Members can help you there!
Before I let you go, I did want to ask if you have purchased the new
Disney Genie+ Service add-on? Genie+ allows you to access the
Lightning Lane entrances for certain attractions, which should help you avoid the standby lines and save time! Another great bonus is that you get unlimited
Disney PhotoPass Digital Downloads with the purchase of Genie+. I have two little kiddos, so any time savings from waiting in line is a MUST for us. If you have not purchased Genie+ yet, you'll need to wait until you are inside either
Disneyland Park or
Disney California Adventure Park and purchase Genie+ through the
Disneyland Mobile App.
I hope this helps, and if you have any more questions, please visit us again!
See ya real soon!
