Do: Download the Disney App
The Disneyland app makes exploring the parks easy by allowing you to look at maps, check wait times, and view FastPass return times quickly and easily. It’s also the tool you need for using the new MaxPass system.
Don’t: Count on the Internet
Unfortunately, you won’t want to count on using the Disneyland internet to run the app. The connection in the parks is spotty at best, meaning your phone data might have to come into play.
