Hiya, Camille! Welcome to
planDisney.
It is very exciting to hear that you are planning to visit the
Disneyland Resort. If you visit this summer, you could see the special
Disney100 nighttime spectaculars. Showtimes are available on the
Disneyland App. There is also
Rogers: The Musical, which just premiered at the Hyperion Theater at
Disney California Adventure Park. This is a must-do for any MARVEL fan!
Regarding your question, you
can upgrade your ticket to a
Park Hopper Ticket in person at the Ticket Booth. However, keep in mind that in order to upgrade your ticket to a Park Hopper, there must be
Reservation availability for the other park. If you have not yet purchased your ticket, I highly recommend purchasing a Park Hopper Ticket in advance. This will save you so much time on the day of your visit!
Tip: If you purchase a Park Hopper Ticket, remember that you can "hop" to the other park starting at 11:00 a.m. once you have been scanned into your first park.
Camille, I hope this helps you! Have other questions? Feel free to come back and ask another question. We are always available to help!
Your Pal,
Alejandra
