Sheesh, there really is some racist views coming out in latter posts.
Also:"But I’m sure it’s a lovely experience walking around the markets, eh?"
It really is. I cannot describe Jma el Fnaa (and the souk in Agadir..the so called Sunday souk) except to say it touches all your senses. It's a cacophony of noise and smells, colours, some wonderful workmanship (Agadir souk is better for this as it has distinct sections and you can see crafts in real time from metal beating to make lanterns, to carpentry making amazing furniture, men making beautiful clothes and doing repairs to clothing, and so much more).
As I said in a post above, I've NEVER had an issue wandering deep into the souks, often away from the tourist areas either alone or with 1 or both daughters. Ironically, the 1 issue was when I was with then husband and we were corralled away from the souk and into a side alley. Soon solved.
I've also stayed in private riads in non tourist areas and have been lucky enough to find amazing local bakeries and even get caught up in a wedding procession in the narrow streets (and was made very welcome) while doing so.
I appreciate some have issues, but in dozens of visits, often solo, I haven't and am going again in Feb, to Marrakech, and staying in a riad just off Jma el Fnaa. I'll be respectful, enjoy watching the bonkers transformation of the square late afternoon (with around 100 pop up restaurants built in just over an hour) and wander around the souks.
