The rate holder of a room rate reservation is the first person entered on the rooming list. However, upon check-in, the first guest to be checked-in becomes the rate holder.
To ensure that there is always a rate holder checked-in and, therefore, the rate is being charged correctly, it is recommended to activate registry key [502149]. With this configuration, the check-in of a rate holder can be cancelled only if there are no sharers checked-in.
