A hotel is a complex operation. It includes places for people to sleep and eat and shop; there are often recreational facilities and areas for public gatherings. In fact, a hotel often can be considered as a small city within its own walls and grounds. Because of its complexity, it is not possible to speak of a single career in the hotel industry; there is instead a wide variety of different careers.
The top people in the hotel industry are managers. The majority of them hold management positions in individual hotels, but some work in the executive offices of the hotel chains.
