Four options, and they have almost nothing in common with one another.
Marrakech City Immersion: Three or four days on the city's food, gardens, souks and architecture, from a riad inside the medina. Cooking classes, craft workshops, tables booked, a morning spent on the buildings. You never leave the city, which is the point. Good for a first visit, and good for a second one with a narrower brief.
Fes Historical Deep Dive: Four or five days in Morocco's cultural capital. The medina with a historian, workshops with master artisans, the madrasas studied properly, the Jewish mellah. It is the densest thing we run in under a week.
Desert Weekend Experience: A Marrakech base with a one- or two-night Sahara excursion. The drive is long and we do not pretend otherwise; the design is about spending the fewest possible hours in the vehicle. Private camp, camel trek, the dunes at both ends of the day, and a bed back in Marrakech at the end of it.
Essaouira Coastal Retreat: Three or four days on the Atlantic. Portuguese-Moroccan ramparts, fish straight off the boats, the painters, and the beach. A slow pace, which is usually the point after a hard week. The medina is small, the restaurants are good, and the town has kept its own life going alongside the visitors.
Each of them is a whole trip in itself.
