Hello, Cathy! Thanks for bringing your question to the Disney Parks Moms Panel. Yay! You will be having so much fun at the Disneyland Resort in just a matter of days!
Disney MaxPass is such an incredible time-saver that I can't gush about it enough. If you haven't yet purchased your theme park tickets, you can add the Disney MaxPass option when you
buy your tickets online. If you already have tickets, then yes, you can add MaxPass once you are in the parks. After your tickets are scanned, open the
Disneyland app and tap the "Get FASTPASS with Disney MaxPass" option. You will need to link everyone's tickets to your app to create a FASTPASS party. You do this by scanning the barcode on your ticket with your smart phone's camera. After that, you will be walked through the steps to add Disney MaxPass to your tickets. Everyone in your party that wishes to select FASTPASSES through the Disneyland app will need to add MaxPass to their tickets.
Once you have purchased MaxPass, you will be free to select your first FASTPASS for your entire party from anywhere in the park. Plus, if you have Park Hopper tickets you can even select a FASTPASS for an attraction in Disneyland Park while you are in Disney California Adventure Park and vice versa. Keep your eye on the time when you can select your next FASTPASS. Once that time has passed or once you have redeemed a FASTPASS, you can immediately select another.
I hope this helps. Have a magnificent time at the Happiest Place on Earth!
