Morocco Solo Female

Planning on taking a tour to visit Morocco in April either G- Adventures or intrepid travel. I want to take an extra day at the end to explore Marrakesh. How safe is it to visit Morroco as a solo female traveller? There are some days where I'd have to go out for dinner alone and free days where i have the liberty to visit the city. Would I be safe navigating the cities alone? Especially places such as Fes, Todra George, Casablanca and Marrakesh?
