We're going to Disneyland this Monday through Friday and I'm not sure how to handle the app/Genie Plus/linking tickets. Our tickets are currently linked under my account. My husband and two teenagers all have phones of their own (plus I have two littles without phones). Do they create their own Disney accounts? If so, can they be linked up to my account and I can purchase Genie Plus for everyone? Or do they just sign in under my account? What's the best way to do this...especially if we get separated and want to ride different rides? Thanks.
