Relatively fixed capacity. Spa capacity
can be measured by the number of treatment
rooms and the time that those rooms are
available (with the added factor of ensuring
appropriate staffing). Most spa operators
approach optimizing revenue by filling the
treatment rooms, but that effort can be limited
by demand patterns and the number of
therapists available. In many spas, the therapists
are specialized, and even if a room is
available, the appropriate therapist may not
be. In the United States in particular, or
where there are limitations on therapist
licensing, it might be challenging to fill a
room set up for facials, for example, when
only body therapists are available.
