I can't give you specific recommendations...every situation is personal. That said, I was in Morocco a month ago. Unfortunately, we didn't make it to Marrakech, which is one of my favorite cities, on this trip. We were in Casa, Fes, Tangier, Chefchaouen and Meknes, plus just briefly in Moulay Idriss, Volubilis and Rabat.

My family loved Morocco and my Mom--who I was traveling with--and I felt very safe during our trip. We saw two protests, though it wasn't entirely clear what was being protested. Both seemed very peaceful (people holding signs, someone with a bullhorn, but not any violence). Additionally, there was apparently a protest in Meknes while we were there, but we didn't see it firsthand.

If I had a chance to go to Marrakech on my most recent trip, I absolutely would have been in the Djemma el Fna. It's a fascinating place.

If I were going back today, there's not much I would do differently. Most of the time (except for Casa and Tangier) we were staying in riads, at which I feel pretty safe. (Many are unmarked and off the beaten path.) I'm not sure if I would feel comfortable staying at bigger, better-known hotels like La Mamounia, because I do think those would be target (though they probably have fabulous security). Additionally, we weren't in many places where tourists gather to the extent they gather in the Djemma el Fna. Probably the most similar place that we visited would be the Place Lahdim in Meknes, which relatively inconsequential compared to the Djemma el Fna.

So there are my thoughts and relatively recent experience. (I do also think there's truth the logic of, "What's the safe day to do fly? The day after a plane crash." Similar, what's the safest time to go to Morocco? Probably today, or in the next month. Security will surely be beefed up.)
