Spa managersstruggle with not knowing whether
or how many guests will show up.
Most spas take reservations to reduce some of that uncertainty, but many allocate a few
slots during low-demand times for walk-in
or last minute business. Reservations give
a spa operator a better idea of when customers
will arrive, but they do not eliminate
uncertainty of arrival, since not all
guests honor their reservations, and others
arrive early or late. In any of these cases,
the spa faces the prospect of unused treatment
rooms.
