What is the reasonable range of hotel labor cost control?

Personally, I think the control range of hotel human resource cost should be related to the type of hotel and the total business volume. For example, star hotels are different from budget hotels, and Samsung is different from four-star hotels and five-star hotels. Generally, chain economy hotels with advanced management concepts will be controlled at around 8%, Samsung will be controlled at around 13%- 15%, and four-star and five-star hotels will be controlled at around 16%-20%. The above is my personal opinion.
