Travel advice, how to travel around the Atlantic coast?

The cities worth visiting from north to south are: Tangier, Alcira, Rabat, Casa, El Jadida, Safi, Sovilla, Agadir, Layong (yes, where Sanmao has been) and Dakara. There are trains from Tangier to El Jadida, so you can play all the way. The longest route from Tangier to Jadida takes about 5 hours by car, and the fare is about 120 RMB. The main means of transportation from the city to the seaside are walking and taxis. Safi, Sovilla and Agadir belong to the south-central, and there are some mountain roads, so the trains can't run. There are many shuttle buses to and from Marrakech every day, and the fare is about 100 RMB. The seaside in the south is very popular, and the hotel industry is also prosperous. You can choose to stay in the local area for one night.
