Which service allows hotel guests to have meals and drinks delivered to their rooms?

The correct answer is room service, which specifically refers to the service that enables hotel guests to order meals and beverages directly to their rooms. This service is designed to provide convenience and comfort, allowing guests to enjoy their dining experience in privacy without having to go to a restaurant or dining area within the hotel.

Room service often includes a menu with a variety of food and drink options, and it typically operates during specific hours depending on the hotel. This service enhances the overall guest experience by offering a personalized touch and catering to guests who may be working, relaxing, or simply prefer to dine in their own space.

The other options, while related to guest services in hotels, do not encapsulate the meal delivery aspect as distinctly. Concierge service focuses more on assisting guests with various requests such as booking reservations and providing information about local attractions. In-room dining could be considered similar to room service but is less commonly used as a term and might include only specific dining options available in the room. On-demand service might refer to a wider range of services that include instant access to amenities or entertainment but does not specifically pertain to food and drink delivery.
