No. It's better described as a Arabic with the vowel-swallowing characteristics of the Berber dialects.
However... there are many modern words that had no equivalent in Darija such as restaurant (because everyone ate at home), so French and Spanish words have been adopted. Ristora for restaurant (could be either French or Spanish origin), semana (Spanish) for week.
I would recommend ALIF in Fez for language courses, see http://www.alif-fes.com/ . I did a six-week course there in Darija. Fez and the surrounding area has a lot more to offer than Marrakech if you are going to be there for several weeks.
"For sheer delight there is nothing like altitude; it gives one the thrill of adventure
and enlarges the world in which you live," Irving Mather (1892-1966)
