Hi Kaitlin! Thanks for visiting planDisney.
Changes to the tier calendar do sometimes happen. However, once you've purchased your Disneyland Resort
admission ticket with a secured
theme park reservation, you're good to go on that day, regardless of whether the tier changes in the meantime. However, since the calendar can change, and prices are subject to change too, I do recommend purchasing your 1-day ticket as soon as you can. That way, you don't have to worry about the possibility of pricing changes affecting your plans to visit.
It is possible to upgrade an unused standard ticket to a higher tier by paying the difference. These upgrades can typically be done in the
Disneyland mobile app, although you may have to call the
Tickets phone line to speak with a Cast Member. If you need to call, they're always happy to assist!
As your visit approaches, check out the
Daily Events Schedule. This handy guide to your day is a great place to sketch out your must-do activities. While these details are subject to change or cancellation, having a rough idea can help guide your choices as you explore everything the parks have to offer!
Have a magical day.
Elizabeth
