Hey there, Jocelyn, and welcome to planDisney!
I love visiting the Disneyland Resort with a group of friends, and I'm happy to report that you can link your tickets together, which can help with things like booking
Lightning Lane return times if everyone in your party has
Disney Genie+ Service.
To do this, you'll want to tap the menu button in the
Disneyland mobile app and then select "Tickets and Passes." On the next screen, you'll need to either scan the ticket barcodes of the other members of your group or have them share the ticket ID numbers with you, and then you'll be all set!
I did this with a group of friends on a visit last year, and it was so nice to not have to be the one in charge of booking our experiences! Normally, I'm usually the one to organize these logistics when visiting, but for this trip, I was able to just sit back and be told where to go and what to ride with our group.
Again, if you're wanting to utilize Lightning Lanes with your party, just make sure everyone in your group has purchased that option! If they didn't add it when they originally purchased their tickets, they can add it after they scan into a park on your first day.
Thank you again for your question, Jocelyn! I hope you have such a fun time visiting the Happiest Place on Earth with your group in just a few short months.
Have a Magical Day,
Greg
