I want him to have his own money to use for souvenirs. But it says he doesn't have charging privileges. Any thoughts?
An MB can be set up to charge to a room account, but I do not think that you can add money specifically to a band for charging. Maybe give him a Disney Gift Card?
Magic Bands do not contain specific information or data on them. They pull from outside data. There's nothing stored on a magic band itself. You can grant charging privileges onto the bands and give your DS a pin at the resort at the time of check in or at the concierge, but there's no "limit" to that. The Gift Card idea may be best.
