Notes: c - number of subcategories in the category; n - number of hotels from each category; m - number managers interviewed in each hotel; c*n*m = number of mentions if each manager mentions each subcategory once.

The number of mentions reflects the total frequency with which each practice was discussed by interviewees. Managers could refer to the same practice multiple times within a single interview, and each mention was counted separately. Thus, the totals may exceed the number of interviewees or hotels.
