Hey there, Ryan!
Thanks so much for stopping by planDisney with this great question. I have a little Mouseketeer who is under 3-years-old, so this was one of the first things I checked about the
Disney Genie+ service.
Ryan, while everyone over the age of 3 must have their own
Lightning Lane entrance reserved through the Disney Genie+ service, little ones who are under 3 are welcome to join the rest of their party in the Lightning Lane entrance.
When the rest of the party is scanning in to attractions like
Dumbo the Flying Elephant, simply let the Cast members know that your little one is under 3 and they will let them through as well. My little one loves to "pretend" to tap her
MagicBand at attractions just like her big brother.
I hope that this answered your question, Ryan!
Have a magical time!
Sarah B.
