I have done my flight training at ACRC (Aeroclub Royal de Casablanca).
The club is based at Tit Mellil Airport, from this point of view is great training conditions, no waiting, you are basically alone in the circuit.
The club has 2 Cessna 150 and 1 C172, prices are quite good comparing with Europe (now about 90 euros/hr in C150 and 140 euros/hr in C172, used to be 75 euros/hr in C150).
Instruction is in French and for ground school, theory, you have to secure your own training materials, you'd better buy them while still in Europe. Useful would be to find your maps, the ones you can buy in Morocco are crap.
Upside: you are doing the flight instruction with fully qualified instructors, mine was ex-military, jet instructor.
Downside is that there are theory exams only 2 times in a year, I have wrote my paper on November 15th, I have not received yet the results...
