Part 5: a day and a night in the city before flying out.
In four hours you can fly to Morocco and it will cost you about £100. You can get a freshly-cooked meal for £3. You can get a room for the night for less than £10 per person. I can’t think of anywhere so different yet so easily accessible (from the UK). I’d recommend it.
Part 4: valleys and villages, deserts and mountains.
Part 3: an overnight camel trek into the dunes.
