Welcome to planDisney, Heather and thanks for bringing a question our way!
If you’re planning to be in charge of making the
Disney Genie+ selections, you may do so for everyone from your device. When making
Lightning Lane selections in the
Disneyland Mobile App, you’ll be asked which members of your group will be included in the plans. If no one else in your group has their ticket on their mobile device, you may scan your device for everyone at the Lightning Lane entrances. Alternatively, the members of your traveling party may scan their paper Theme Park Ticket or their
MagicBand+.
So, while each Guest in your traveling party is welcome to scan in at the Main Entrance and Lightning Lane Entrances, they are not required to do so. You may allow the Cast Member to scan everyone’s tickets from your device.
I hope this helps! Have a lovely time at the Disneyland Resort!
