Hiya June!
Welcome back to planDisney! June, I sense a fellow planner and family team leader. You have taken on the noble task of booking all of your family's tickets and events and are even willing to share your My Disney Experience Account! You deserve a lovely yummy treat for all your work. Make sure to share this answer with your family as a hint. *wink*
I have good news, my friend, those family members who want to make their own
Lightning Lane selections on Genie+ don't need your account as I highly recommend that either each adult or at least one adult in each family group make their own
My Disney Experience Account. I would then make sure to link each other on the
Family & Friends List. Your shared plans will show up on each other's accounts. If any family group wants to make their plans by booking different Lightning Lane return times they can do that. During the process of finalizing their selections, they will be able to choose who they want to join them by checking them off from a list.
I don't know if you have planned any of your dining reservations but may I suggest
Biergarten Restaurant at EPCOT? It has been pretty great for myself and other panelists who have a large group that wants to eat together. Just be mindful that from July 17 to July 29 the dance floor will be closed for refurbishment. Another restaurant that has surprising availability for larger groups is
Ale & Compass Restaurant located at
Disney's Yacht Club Resort. It's within walking distance from the International Gateway entrance at EPCOT.
I hope this helps and that you have a magical time. Feel free to come back again if you have any more questions!
Happy Planning!
