Hi there, my husband and I are planning a trip from Fez to Marrakech including a stay in the desert. We've been doing some research and would like to join a tour. We've been quoted 400 Euro per person for a 3 day trek, or 500 Euro per person for a 4 day trek. Does this price seem too high--my feeling is that it might be. Also, how can I negotiate the prices over email? Many thanks for your help.
