I had to look it up, having lived in the south but never hearing of an “outdoor room”.
An Outdoor Room has walls around it and is only partially roofed; while a Public Outdoor Room has a roof, but essentially no walls. Therefore: Build a place outdoors which has so much enclosure round it, that it takes on the feeling of a room, even though it is open to the sky.
So it’s basically not a room, but the outdoors, some roof with walls?
Or a roof but no walls. Don’t the skeeters eat you alive?
I was referring to old hotel rooms that had the door that opens to the outdoors. Not a hallway hotel.
