A Good Introduction to Morocco
Marrakech can seem intimidating, but it is a very accessible city for tourists and extremely safe, with the only downside being the amount of people trying to get you to give them money. The souks and main square Jemaa el-Fnaa are its most notable features. Overall, three full days should be more than enough to experience all it has to offer. Two days is enough for those not interested in visiting all the historical sites, of which there are not many.
Insider Tip:If you're a girl keep your hands in your pockets while walking through the main square unless you want Henna. Expect the prices of items in the souks to be at least three times more then they are worth, some times as much as ten, and be prepared to haggle your way down. Paying anything more than half the initial asking price is overpaying.
