The whole reason I had asked the Riad al Badia to book me a guide in Marrakech was because I was afraid of getting lost. I'm not usually a scaredy cat when I travel but then again, I mainly travel to Europe, or the US - places where it all feels very familiar. Practically everybody in Europe speaks English and if they don't, I speak fair French and an ever-growing smattering of Italian. It also comforts me that I can read French, Italian and Spanish pretty well, which seems insane, but it's true. I remember having a bit of a panic attack in Croatia because I couldn't read the street signs. It's a Cyrillic alphabet and my brain has no way to frame the words. I can't pronounce them or break them down or hold them in memory. In Morocco, Arabic is the primary language. Many Moroccans also speak Berber. Many speak French and English as well, especially in the souks and more touristy sections but still, I was afraid.
I did a bit of research before I traveled to Morocco, and read the stories about single woman traveling alone in Marrakech, plus some unpleasant stories about harassment in the souks and yet more stories about travelers being misled when they asked for directions, and instead of ending up back at their hotel, they were taken to a spice or rug shop. I'd like to shrug all that off, and I might have, if I was still in my 20s, but I'm not, and I didn't. A guide seemed like a panacea to all problems. I would have a local man with me, an official tour guide, which would prevent the harassment. I'd be taken only to the most reputable souks, I wouldn't miss any of the historic sites in the city and I would absolutely, definitely not get lost.
I'm going to highly recommend that if you travel to Marrakech, you hire a private tour guide. Ask your riad or hotel to set it up for you, which will ensure that you get a reputable, certified guide at a fair price. My guide Aziz and I practically ran through Marrakech, pausing briefly now and again when I just had to take a few more pictures. But I didn't get lost. And that was worth it.
