Tourists from First-World countries want a different kind of experience.
Something challenging. Something out of their comfort zone.
This is exactly what a third world country like the Philippines can give them!
Can they survive... a hike on Smokey Mountain?
Can they make it through a night in a "hotel in the slums? Can they walk unscathed in a snatcher-infested barangay? Can they swallow the exotic pagpag?
Tourists will never see the world the same way again!
