First of all, I made the error of giving my youngest niece and DD charging privledges and I do not want them to have them. I am sure you must be able to change this and, if so, how? Next - my DH is paranoid about our eldest niece having her own KTTW card... she is 12. As I understand it, the pics taken at port are associated with the card so nobody else can steal the card and use it. However, I want to know if the room number is displayed on the card and does the KTTW card double as a room key? TIA!
