Enjoy! Morocco is a starkly beautiful place. Make sure to get out of Tangiers and head down the coast then into the interior (Marrakech and Fes are both really cool).
Do NOT give anyone your passport...even for a moment, no matter what their freakin story is, no matter what their title is. If you travel with a woman NEVER leave her alone. Some dudes tried to kidnap my wife and her girlfriend when they went to Morocco.
