Hi Tammy!
Welcome to the Disney Parks Moms Panel. The
Disneyland Mobile App will be such a handy dandy helper during your visit to
The Happiest Place on Earth and I'm glad to see you are already using it to plan from home!
Not only is it okay to link your
Park Hopper Ticket in advance, but I recommend it! I just feel like it's so much easier to have everything loaded and ready to go before even boarding the plane. Your ticket will not be activated until you scan it for entry into either
Disneyland Park or
Disney California Adventure Park. When you do, a friendly Cast Member will take your picture on a small hand held device and this will link your ticket to you for the remainder of your stay. You can also link your ticket into multiple different accounts, so if everyone in your family wants to download the Disneyland Mobile App onto their own device, you can! This becomes especially helpful if you've added
Disney MaxPass to your ticket and will be able to book your
FASTPASS reservations as a group from your smart device.
I hope this helps in planning your upcoming visit. Please come back if we can help in any other way!
