One of the largest hotels ever created, Hotel Extraordinaire is the size of a large city. Anyone can find a room there, and most people can find two. It's one of the places people generally go when they need to meet someone. Watch out for the staff, they can be rather... unsympathetic to the law...
The City Streets of City World are easily likened to the Underworlds of mythology. People are in a constant state of fear, crime is ignored and fights are the only thing to do. Many of the Solar System's most notorious gangsters operate entirely in the City Streets. It is not a place for the light-hearted.
