Welcome to planDisney, Shannon!
It sounds like you are planning to visit the Disneyland Resort soon!
Theme park tickets are not mailed, so you will use the eTickets that you have linked to your
Disneyland app to access the parks. You will receive a paper ticket the first time you enter the park gates that you can use for the remainder of your trip or you can continue to use the tickets in your app.
Have you had time to explore the other features of the Disneyland app? If not, I suggest familiarizing yourself with the app before your trip. It will be your best tool for navigating the parks efficiently. It will show current attraction wait times, allow you to mobile order food from a variety of quick service locations, and it will be how you use the new
Disney Genie service that will be debuting sometime this fall. We don't yet know the official date that Disney Genie will launch, but we do know that it will be a complimentary digital feature within the Disneyland app that will create personalized park-touring itineraries based on your interests. You'll also have the option to purchase Disney Genie+ for $20 per day, per ticket. Disney Genie+ will allow you to select the next available return time for an attraction and then skip most of the wait by using the Lightning Lane. If this feature becomes available before your trip, you'll definitely want to be ready to use it!
I hope this helps. Have a splendid time at the Happiest Place on Earth!
