We (me, my wife, our 10-year old son, and another couple) will have 2 weeks in Morocco in April, 7 days of which will be driving between Marrakech and Fes. Can anyone tell me approximate driving times between Fes and Merzouga, Merzouga and Ourzazate, and Ourzazate and Marrakech? Also, what places between Fes and Marrakech (other than Merzouga) are worth visiting (we don't have much time so we need to stick to the highlights)? Are there any riads/hotels that you can recommend along the way? Thanks in advance for your help!
