Hello, if we book 2 rooms for the same night (2 people per room) under the same Diamond member's account, will they extend the Diamond privileges to both rooms? I'm assuming free breakfast + exec lounge access?

Alternatively, if we book a room under a Diamond member's account with additional guest(s) listed, but only the guests are present (and not the primary member), will they care? I know in the USA, no one does. But like Europe, I assume Japan takes copeis of passports, so I'm not sure if they care if the primary person on the reservation is present.

Thanks.
