Some more info. First, they do not deliver purchases to your room, they deliver them to your resort where you can pick them up the following day. Also, you can control which MB's can be used for charging. i.e. I did not allow charging for my DD's when they were toddlers. The part I like best is that, since my DW does not carry any CC's, I would always have to be there or remember to give her a CC. Now, any one of us (including our DD's) can buy something without needing a CC. Also, to use the MB, you need to enter in the PIN code, that you set up for it, to make any purchases. We always use our MB's to charge back to our room and love it, especially our DD's.
