We went to the medina in Marrakesh in March this year. I found it far less threatening than the medina in Fes. There is more room to move around and you are not getting almost run over by mules all the time. The people are friendly, however be careful not to be conned into buying items that you don't really want. The stall owners can be very pushy and all will tell you that their goods are unique, however you can often find the same item around the corner and often cheaper. Haggling over prices is expected so don't pay the asking price unless you are totally happy that it is already a bargain.Do be careful where you eat, look at the food and then look at the cafe/restaurant, is it clean does the food look fresh. Be careful of the monkeys, they are trained to steal off you if they can while they look cute they are cunning and sometimes can scratch or bite and that will only lead to severe medical problems.

Over-all we had a good day in the medina but did find that the further you went in the less variety there was as everything was the same. If you want to see as much as possible then start early (they open about 10am) and take some food and water with you, the stores don't close until about sundown so you should have plenty of time BUT do take note of which way you are going, it is like being in a rabbit burrow. Be mindful of those around you and hold on tight to your belongings,one last thing...those anying people that follow you around and try to sell you there goods...don't look at them and just keep on walking, this worked for me others in our group tried to argue with them and this only leads to you wishing you simply had shut up and kept walking. They will argue with you and follow you for ages, I witness one fellow follow a man in our group for over five minutes.

This is an experience that will stay with you forever, if you have the chance then you simply should not miss it.
