I did a two weeks trip by car throug Morroco. Driving was no problem at all. The police/royal gendamerie is very professional and does not do bother you. As soon as they see that you are a tourist they leave alone. I had no problems at all unlike some speeding Morrocan taxi drivers.

I can highly recommend the Riad Boustan in Fez. Great place and very friendly owner who is a Morrocan from London. Very helpful chap. I also recommend to get a guide to explore Fez. Just ask the place you stay to get one for you. The price is 25€ for a whole day and it really worth. My friend and I paid the guided at the end 40€ including some museums entrances and a generous tip because he was a really great guide. He did not only showed us the old town but since we had a car drove with us to some places outside the city. Yes of course you will also visit a carpet shop, a fabric place and a pottery place but first of all you not forced to buy anything and second you don't get any better handcrafts than in Fez. The quality in Fez is much better than for example in Marrakesch.
