Tourism is one of the fastest growing industries in the world. Although people have been traveling from one place to another since time immemorial, tourism industry has experienced a spiraled growth owing to improvement in transport and communication technology.
Tourism can be defined as traveling for the purpose of recreation, leisure, business or any other purpose which is not considered a routine. This means that although people have been traveling from one place to another, it is the precise definition of the purpose of traveling and time limitation that differentiates between usual traveling and tourism. There have been an increasing number of tourists each and every year. For example in 2007 the number of tourists grew by more than 6.6% to 903 million arrivals compared to the 2006 statistics.
