Where to Stay: With such a big crew we stayed at three different Riads (basically Morocco's version of a Bed & Breakfast). All three of them were awesome and come highly recommended. Riad Goloboy had the coolest interior design, Riad Sashema was super chic with a Parisian feel and Riad Anya was best for a "house" party with big groups! They were all across the street from each other so we never felt isolated.
I have a love/hate relationship with the tanneries of Bab Debbagh. Mostly hate, but its a must see when you visit Marakkech.
Here's a tip: Avoid getting scammed in the tanneries!! Whatever price they suggest first, only offer 10% of that number at most! You can get some nice pieces just not for highway robbery prices.
