I have to agree with you particularly when it comes to the security issue. When I was on the Victory, the room number wasn't on the S&S card. That provided some security. But there was still risk. If you lost your card, all anyone had to do was order a drink on your card; when the receipt came, it had your room number on it, that I didn't like. I don't understand why the room number had to be on the receipt. The cash system would avoid this risk.
