Round-the-world trips may be hard to manage, but people from developing countries can often still visit neighbouring developing countries visa-free. For example, Indians have visa-free access to much of South and Southeast Asia, while Moroccans can go to West Africa either visa-free or for a visa that is always granted. So, when people from these countries get into these forms of travel, they often do take advantage of this to explore the neighbours.
