Fez is a great place to visit, my advice to anyone is get an official guide. The place is busy and you can get lost in the medina easily. We went for an unofficial guide and all I can say is, it’s not worth the few euro savings. I think we missed quite a bit of the main stuff and he took us on detours to avoid the tourist police.
Morocco is a great country to visit, one of my favourites in Africa. I hope I can get back there soon, now that I know what a tripod is for.
