Hi Christine!
Welcome back to the Disney Parks Moms Panel! I love using
My Disney Experience to keep track of not only my plans and reservations, but those of friends and family traveling with us. It is great to be able to log in a see and plan everything all at once. This question is a bit tricky because there are really two answers. If your brother made the reservation and his family is listed under his reservation on his
My Disney Experience account, then yes, his family members should be connected to you through him. The only exclusion to this would be if his wife or any of his kids have created their own
My Disney Experience account. If they have their own account which they can log into through their own email, then yes, you will have to request them as well.
I hope this makes sense, but if you need any clarification or there is anything else you can visit the
My Disney Experience Help Page or
please send me another question.
Have a wonderful vacation!
Magical Wishes,
Lauren
