i spent 11 days in Morocco in late Oct - early November 2006... a magical place...
my girlfriend and I brought the following with us:
SWC
M3/ Bessa L with 21/50
F100 with 35/2
Yashica T4
If i could do it over again, I'd take the SWC, Gr1S (instead of the T4), R2A with 21/35/85 lenses... (fast lenses are a must in the medinas where the walls are high and light doesn't get a chance to get in)...
bring something that is a fast p&s if you want to shoot people... or if you choose to respect them, don't shoot people at all as it was my experienc that most didnt want their photos taken (i asked)...
some pics from our trip can be viewed here:

my advice is to travel light (less is definitely more in a country where you will likely have to rely on notoriously unreliable pubic transportation - we got stuck on a bus in a small mining town due to flooding, another bus we were riding on burst into flames and was evacuated, typical intercity taxi seats 7 (including driver) in cars designed for 5 (window cranks in the back are removed to make a little more room)... bring lots of ziplock bags, duct tape and/or electrical tap, a light tripod and a well sealed camera bag... (fine sand permeates the air)...
highlights - Chefchouen, Fez, the Djamma el'fna in Marrakesh and the Sahara - accessed by way of Zagora...
have fun and feel free to send me specific questions...
