When considering kiosks, staff presence can't be completely eliminated. Minimal staff will be required to deal with mechanical issues such as missing supplies or paper jams. They also play an important role in training on usage of the self-service check-in and resolving any guest issues. As the kiosks functionality at the hotel gets more robust and guests become more familiar with them, staff presence at the kiosks can be gradually reduced and diverted to service points which require greater personal interaction. A ratio of staff to the number of kiosk terminals can be determined based on the usage patterns of the kiosks at each property.
