I am going on a trip to Disney in late October and will be receiving a new MyMagic Band which will have my tickets linked to them. I plan to utilize my FastPass+ reservations online to secure Fast Passes that will be linked to my new MyMagic Band. My question is that say I have an older MyMagic Band that I used back in June, could I bring that older MyMagic Band into the park and visit a Fast Pass kiosk to obtain 3 Fast Passes for that older MyMagic Band? I would then have 3 linked to my new MyMagic Band and 3 linked to my older MyMagic Band. I understand that you don't have to link your tickets to your MyMagic Band currently, so how does the FastPass kiosks recognize the difference between a new MyMagic Band that don't have tickets linked to it and an older MyMagic Band? Thanks!
