I'm moroccan, so I know what you're affraid of. Everything they told you here is real. You can meet cool people. Enjoy the country etc. But you may also have bad experiences with cops trying to get some money, or false guides expecting you to follow them somewhere you don't want to. So, rule nº1, never leave the raods on your own. Try to take a trip with 2 or 3 cars. It's more safe. Rule nº2, as a woman, you should know that you are visiting a country of islamic machos. Although we are not in Iran, you'd better take your husband or boyfriend (or brother aswell) with you. Rule nº3: don't dress too sexy, its not a good idea.
Maybe you will find yourself more confident after a few days. Then you can enjoy the travel, knowing how to behave depending on the places and situations.
Excuse my bad english.
