For a 9-hour layover, visiting the Hassan II Mosque on the coast or a quick trip to the city center might be feasible, but check operating hours and allow ample travel time to return to the airport. Factor in immigration and security procedures. Alternatively, an airport hotel can offer a convenient option for rest and freshening up. Casablanca Airport itself is relatively compact, and transit between terminals (if applicable) is usually straightforward. Note that while the airport is described as efficient, the city's attractions might have limited opening hours, especially in the evening.
