Hey there, Laura! Thanks so much for stopping by planDisney with your planning question for us!
Your visit is quickly approaching and I am so excited for you to experience the magic of Disneyland Resort! I love that you are thinking ahead and wanting to make sure that you and your friends can enjoy the day together. When I head to the parks with a group of friends, we designate a group leader to be in charge of the group for purposes like
Disney Genie+. For this, one person would just collect everyone's ticket ID numbers so that they can add those tickets to their Disney account in the
Disneyland app. Or if you want until you are all in person together, the group leader could scan the ticket barcodes from each person's app to link each ticket. This means that the group leader could then make Lightning Lane selections for everyone in the group if you all purchase Disney Genie+.
Reservations are not linked between groups, so only the person who made the reservation would see that in their Disney account. This person would be the one to check in when the reservation time arrives. These would be the things that you'd book for your group, everything else can be individually done through the Disneyland app.
Laura, I hope this information helps. I hope you and your friends have the best time at The Happiest Place on Earth!
Carrie
