It wasn't too long ago in human history that people rarely, if ever, traveled beyond the village they were born in. We've come a long way since then: according to the World Tourism Organization (WTO), international traveler arrivals peaked at 763 million in 209 countries and territories in 2004. The WTO expects that number to reach 1.6 billion by 2020, making international travel one of the fastest growing economic sectors.
