Hi there, Aleia, and welcome to planDisney!
Thanks for submitting your question to us and how exciting that you'll be traveling with your family to the Disneyland Resort for a
Holiday Season visit! Even though it's Southern California, the Cast Members do such a wonderful job with decorations that the entire Resort feels like a festive Winter Wonderland.
It sounds like you've done everything correctly, Aleia. Linking all your family members together on your account will set you up nicely to be able to book
Virtual Queues and
Lightning Lanes for them on the day of your visit. Be sure that you have the
Disneyland Mobile App downloaded to your phone ahead of time.
I'm afraid that
dining reservations are only visible to the MyDisney account that made the booking. At the time of this writing, there is no way to share them online or within the Mobile App with another MyDisney account even if they are linked to you. I often recommend that large groups share a separate Notepad document detailing everyone's plans that can be edited by the group. I realize it's a bit of a clunky workaround but at least everyone's plans can be included and kept up to date.
Since everyone is linked together, it'll be easier for you to grab a Virtual Queue for your group. Currently, that's the only way to experience
Haunted Mansion Holiday. By the time of your visit,
Tiana's Bayou Adventure will have opened and will use Virtual Queue and be available on
Lightning Lane Multi Pass.
Aleia, I wish you and your family a magical Holiday visit to The Happiest Place on Earth! Please let us know if you have more questions and we'd be happy to help. Until next time!
Wishing You a Great, Big, Beautiful Tomorrow!
