Every now and then, some people make out like a bandit by taking cash in lieu and flying home, but I feel it's rarer than people thinking and with smaller profit margins. Most people that I know took their cash in lieu so that they can use the money for a trip or an indirect flight home.
That's what I'm doing. Rwanda, Thailand, Singapore, Malaysia, Cambodia, Vietnam, San Francisco, Minneapolis. All for not much more than a flight straight home.
