The term 'SKYLIT HOTEL LOBBIES' can be summarized as a type of hotel lobby that is illuminated by natural light from the sky. An atrium is a large open space, often located in the center of a building, that is surrounded by other rooms or stories and is usually topped with a skylight to allow natural light to enter. Skylit hotel lobbies are typically designed with an atrium in order to create a bright and airy atmosphere for guests.
