What are the main components of hotel revenue?

Room revenue, food and beverage revenue, and other operated departments represent the primary sources of income for hotels, making this choice the most accurate.

Room revenue is the most significant portion of a hotel's income, stemming from the sale of guest accommodations. Food and beverage revenue comes from restaurants, bars, and room service, which are essential components of a hotel's offerings, catering to both in-house guests and outside customers. Other operated departments include various auxiliary services such as spas, retail shops, and recreational activities, further contributing to the hotel's overall revenue.

In contrast, the other options mention sources that may not directly align with the core operational revenue streams of a hotel. For instance, while advertising income, membership fees, and vending income can contribute to a hotel's finances, they are generally not considered main components of typical hotel revenue, which primarily revolves around services directly tied to hospitality and guest experiences.
