Visited Morocco some time ago for one month so spent some time in most places. Tangier was worth a couple of days. More time at Essaouira (great), down to Agadir (okay), a fair time in Marrakesh and Fes (must sees), and a week in Chefchaouen (very special). Enjoyed walks in the countryside there, and the most relaxed place in the country. Then headed across to Algeria (a whole other story - not a safe place at the time). Always wanted to go back to Morocco. Can be a very hectic place, but with the extra time up my sleeve, never felt rushed and was happy to just wander around and meet people (Fes is one place it's easy to lose a whole days in just wandering. Aside from the touts the people are friendly and helpful.
