It’s taken 82 years, but travelers are finally discovering that Morocco’s largest city is much more interesting than the fictional version conjured up at the Warner Bros. studios in 1942. Casa, as the locals call it, is the display window for modern Morocco. Now, the city has a hotel that mirrors its ambitions. A new outpost of the Royal Mansour, owned by King Mohammed VI, follows up the five-star Royal Mansour Marrakech, which opened in 2010 and now ranks No. 23 in the most recent ranking of World’s 50 Best Hotels. The Royal Mansour Casablanca’s interior design skews Art Deco, and its mustard, scarlet, burnt orange, olive green, ash gray, and cinnamon interiors nod to Morocco’s well-known spice merchants and souks. But the hotel’s most important amenity is that it has the keys to unexpected delights. In addition to the usual tours of souks and monuments, the Royal Mansour can arrange for more immersive experiences in Casablanca’s culture—for example, a tour of the city’s street art with Alouane Bladi, a nonprofit organization that has worked to make these outdoor murals a signature of the city. —Alexander Lobrano
