Hey there, Julian!
Welcome to planDisney and thanks for dropping by with your question!
It may be possible to upgrade your tickets to include the Park Hopper Option. But, you must request this change at the
Disneyland Resort Main Entrance Ticket Booth. And please note, this upgrade is subject to availability. Prior to your arrival, please check the
Availability Calendar to see if Park Hopper Tickets have available reservations on your desired date.
The Disneyland Resort offers three
parking areas: Mickey & Friends Parking Structure, Pixar Pals Parking Structure and Toy Story Parking Lot. Your pre-paid parking may be used at any of these parking areas. Plus, you are more than welcome to leave and return later in the day. Just be sure to keep your parking receipt and show it to the Cast Member when you return.
If you have more any questions, please race on back to planDisney!
