Greetings, Maddie!
I'm so glad you stopped by the Disney Parks Moms Panel. I'd be delighted to help you with your question regarding
park tickets at the Disneyland Resort.
You most certainly can upgrade your ticket to a Park Hopper ticket as well as increase the number of days if you are interested in doing so. This type of upgrade must be handled at the Main Entrance ticket booths, so make sure you arrive early! Just let the Cast Member at the ticket booth know you would like to make your upgrade, and you will only have to pay the difference in price for your new ticket.
I'm so glad you decided to upgrade to a Park Hopper ticket, because park-hopping is SUCH a breeze at the Disneyland Resort. With Disneyland Park and Disney California Adventure Park only footsteps apart, it makes it so easy to jump between parks all day. I always get the Park Hopper option so I can take advantage of shorter wait times throughout the day when I see one on the
Disneyland app. I also love the freedom park-hopping gives me to meet Characters when available at either park as well. Sometimes I might be in Disney California Adventure Park but get the craving for Plaza Inn's famous fried chicken, so I can easily head to Disneyland Park to satisfy my craving. Alternatively, I might be in Disneyland Park but in the mood for a Carthay Circle Lounge cocktail, so I can easily hop over to Disney California Adventure Park for this.
I hope this helps, and please return if you have any other questions. Remember, Adventure is Out There!
