Why is the room occupancy rate the main economic index of the hotel?

Whether the hotel business is good or not depends on the room business. If the price of 20 rooms is calculated according to the price of 400 people, the daily income is 8 thousand. All it takes is two cleaning aunts. The salary for two people is up to 200 yuan a day. Many budget hotels are responsible for more than 20 rooms. The linen washing in the hotel breakfast is about 100 yuan, which means that the profit of a room is around 300 yuan. Hotel catering department is the department with the largest number of people in the hotel department. If the food and beverage department earns 8000 yuan, it needs far more human and financial resources than the guest room.
