No industry in the world employs more people or is the world's largest foreign currency earner than tourism. Long billed as the cleanest industry for developing countries to invest in, tourism seems to offer everyone involved a positive experience. This is the official line, anyway. In truth, the reality is much more complex . For The Final Call Hickman travels the world on a range of holidays to find out what this industry is really like. We hear from everyone - the holidaymaker, the hotel manager, the waitress, the disillusioned travel agent, the exploited prostitute and the angry local politician to discover what they don't tell you in the glossy brochures. Behind the sunny facade of pools, smiling locals, sightseeing trips and exquisite cuisine is an ugly reality and it is spreading unchecked to all corners of the globe. But none of us are going to stop holidaying and at the heart of this is a heartfelt attempt to discover the best way to holiday wherever you are.
