Hey there, Janette! Thanks for bringing your question to planDisney. Sounds like your son has a fun day planned with pals at the Happiest Place on Earth.
If one of his friends has a mobile phone, they can link your son’s ticket to their account, so they can make
Disney Genie+ Lightning Lane reservations together. With the ticket linked, his friend can purchase Genie+ for him. In the
Disneyland mobile app, his friend will need to go to Tickets and Passes and can link the ticket there by scanning the barcode or entering the ID number manually.
Also, your son will be able to use cash at Disneyland Resort, but you could also consider purchasing a
Disney Gift Card online in advance and print it out for him at home. He can use this to make purchases during his visit.
I hope your son enjoys his trip to infinity and beyond!
