Daughter’s Choir Ticket, Genie+ and Friends

[Carrie in AZ]

My daughter will be at parks on Fri and Sat. with her school’s Choir. Does anyone know if I can link her group ticket to my account or if she can set up her own account and link three friends as well so she can manage Genie+ for her small group? I want to treat for four of them. Has anyone ever done anything like this? Thank you!
