Hi Patty,
Thanks for visiting the Disney Parks Moms Panel and for sending us this excellent question!
The short answer is a resounding YES, absolutely! Once you linked both his admission ticket and the retail MagicBand via
My Disney Experience account, both components became automatically associated with each other.
MagicBands added to My Disney Experience accounts displaying an "active" status, will have the admission ticket information on it too. Since your grandson's new MagicBand is already linked via his My Disney Experience account, that action has already taken care of it and automatically reflected his theme park admission.
Did You Know? When staying off-property, you may
select FastPass+ attraction experiences and FastPass+ entertainment options 30 days prior to the start of your vacation. Any FastPass+ attraction experiences and
FastPass+ entertainment options chosen will also be linked to MagicBands via the My Disney Experience account.
I hope this was helpful information, Patty. Please come back to visit us again soon, during or after your vacation to the Walt Disney World Resort. My Moms Panel friends and I will be thrilled to help you discover the
Power of Magic while planning an enchanting Disney vacation!
Ritzy °O°
