I did this trip with Exodus 2 years ago and had a great time. There were only a few technical sections (could be avoided if you wanted) and one lllloooonnnngggg climb (over 1000m height gain in 15km on a rough track - took me 2.5 hours) up Tizi'n'Tazzarzet from Bab'n'Ali (optional - you could ride up in the landrover).
