I am planning an August trip w/son and 11 yr old son. We would like to fly into Marrakech and then do a desert trek. We would also like to go to Fes to see the tanneries. We would plan on 10 full days. My questions are: is this doable w/out being too rushed. If so, any suggestions as to an itinerary. Can 11 yr olds do desert treks? Also, should we rent a car or look for tours out of Marrakech? I also hearing there is rafting - anyone familiar with this option?
