Travel is the relocation of individuals between different geographical locations. Travel can be done with just feet, bike, car, train, plane, train or other means, and is either one way travel or circular journey. Most people take a mixture of public and private transportation to get around; buses, trains, subways, taxis and even shuttles, planes, trucks or cars. There are also airlines that offer flights and other modes of transport for a fee and/or in packages. It may include activities like sports like trekking, mountain climbing, and golf; outdoor activities such as hunting, fishing, hiking, camping, bicycling, horseback riding, paragliding, rafting and skiing.
Traveling has become an important segment of the tourism industry. Many countries depend on tourism as a major source of income and a major source of their budget. As more people travel to different countries, the need for hotels, travel agencies, restaurants and bars, travel tours and related services increases.
A successful tourism industry depends on long term investments and the continuity of tourism through periods of financial downturn. Tourism may be a very predictable business; however, short-term fluctuations in the tourism industry may cause severe damage. Short-term fluctuations in the tourism industry may result in the reduction of spending power of travelers, decreases in the number of tourists visiting that country, decreases in the number of hotel rooms available for rent, or change in flight schedules and routes. These short-term changes affect the amount of money that travelers spend, the quality of the accommodation and services provided and the level of enjoyment travelers experience when they travel.
