I remember a question I had. There can be “resting spaces” / “lounges” with no services and amenities in attractions and tourists spots, especially large =museum and =place_of_worship . They are akin to a mix of no-service mall lounge, passenger waiting space, and =shelter but it’s often wholly indoors or attached not a standalone structure.
Anyway for something on topic, some airports call their free sleeping space “lounges”. It’s another mix of resting space, and waiting space.
