Do you know which hotel and room your girlfriend is staying in? Can you ask the front desk for a room card?

The front desk can only confirm that it is a room occupant, and then help open the door. The front desk card can't be checked out.

In principle, the hotel keeps the information of the guests confidential, and the front desk staff of the hotel cannot tell the information of the guests to others in any form.

If you need to keep your room confidential, you must inform the front desk, and the front desk staff will treat your room as a confidential room. Anyone who asks about this room won't tell anyone.
