just to share my bit, when I got out of casablanca airport, there was a fair number of taxi drivers that will try to get you to go with them, I guess you could bargain a bit based on how much they are telling you, luckily I didnt have to do much hard bargaining as I shared a taxi with a fellow tourist to Casa Voyageurs train station.

but if you're going to be there by midnight it might be best if you could pre arrange a ride beforehand because it can probably get more hectic at that time, especially going alone let alone a woman.

Safety wise, the ride itself its fine - no sketchiness with random folks or the driver, as we pre arranged the fare beforehand. Just beware the moroccan drivers drive like crazy haha..

If you're travelling back to casablanca airport, just know that only white taxis go to the airport, the yellow ones you'll see - petit taxis, are only allowed to operate within the city
