Suzann,
At this time you cannot pair the
MagicBand technology with a smart watch. Believe me, as an avid Apple Watch wearer, I can say that this would be a great thing!
But no worries, the Panel is here to the rescue!
So the
ShopDisney online store has a
MagicBand section that has lots of different bands you can purchase. But also there you will find a
lanyard 'medal' where you can remove the core 'puck' from the middle of the MagicBand and put in this medal that can then be clipped to a lanyard, or a belt loop or similar location. This is just one of a few similar items they have in the stores at the resorts and parks down at Walt Disney World.
I also found another solution. There are a lot of home crafters that have created similar 'medals' that will then clip on to the band of my Apple Watch. The one I bought was VERY secure, and it resulted in me having only the one watch band, with both my watch and my MagicBand pass together.
Have a Magical Vacation!
