As the PP said, you can't charge to your magic band. BUT - the easiest way to deal with this (so you don't have to pull your wallet out at every booth) is to get one of the gift card bracelets. Oh dear, now as I'm typing this, I don't know if they have them this year, but I hope so. Anyway, you can preload a $ amount on the gift card and it hangs on your wrist. All the booths took them the last time I went. And if I under guessed how much I was going to spend - you can go put more money on it at any shop. And if I over guessed, I just had money on a gift card I could use any where. Or save for the next trip.
