This was 2 years ago almost. We did not go to the front desk to set up charging which is a time saver. That is what I am trying to say. My brother was on his account in our room. He controls his bands (not me) and his charging (not me). When he is in my room I control online check in for anything under my name (and being DVC he is often in my villa) but he controls everything under his, including his own band. I cannot look at his bands, his charging, his anything. I can add him to my rooms and my ADRs and yes, his bands ship to me when he's in my reservation, but that's it.
It was very nice to not to have to deal with it like we did the previous time as it took time to set it up only to have it not work right, and then go back and fix it after. Which the band ID was used to find out who made the charges so they could easily just transfer it back to the right card, but still 10 minutes I didn't want to deal with again
