I apologize about all the questions but I'm completely unfamiliar. I will be traveling to Marrakech from Casablanca in July. Can someone explain where the train station is located in Casablanca in relation to CAS Airport? Should I buy tickets in advance? Approximately how long is the journey? Do trains run all day and night?

I think and will be staying Marrakech for about six days before movnig on to my next destination. I was wondering whether I have enough time to do an excusrion to the Atlas Mountains or desert? I'm obviously pressed for time and what to make the most of it. Any suggestions would be more appreciated, including recommendations on accomodations in Marrakech.

Thank you in advance!

Be prepared for a wait at immigration, there are often long queues and not enough officials. Trains from the airport to Cassa Voyagers station take 45 minutes, I think they run hourly, From Cassa Voyagers to Marrakech takes 3 hrs 15 Min's, and leaves every 2 hours. Should you miss the train there are plenty of tea shops in the area for relaxation and people watching.
You will find the timetable at http://www.oncf.ma/En/horraires.aspx?ep=7&elt=26&CodeRD=0093&CodeGD=00200&CodeRA=0093&CodeGA=00110&heure=0000&date=23/05/2008

You will have plenty time to see Marrakech and visit the Atlas mountains, there are plenty agencies booking trips.
