Roommate

A guest who shares a hotel room with another guest in a block — the second, third, or later occupant on the same reservation, listed on the rooming list under the primary guest's room. Shared rooms are how most crews, teams, and departments hold cost down, so a roommate is not a guest of the primary guest but a traveller in their own right: the hotel needs every occupant's name before it can check anyone in, occupancy drives bed configuration, and the room nights stay committed whether or not the second bed fills. A room can carry up to five occupants, bounded by the room type's own maximum, and each occupant is a record of their own — carried through to the hotel's list, the printable version, and the rooming-list audit, and reachable by a personal link of their own for contact and travel details. A roommate who joins or leaves after the list has gone out reaches the hotel as a name in the change notice, not as a difference the front desk discovers at check-in. Loyalty numbers belong to the primary guest, since that is the account the stay credits, and where two departments share the cost of a room the split is reporting only: it never changes who owns the room.
