Travelling is one of the most popular forms of recreation in the USA. Most American employees receive an annual vacation with pay. Travelling within the country is popular because foreign travel generally takes more time and money. However, Americans who wish to vacation outside the USA are free to go almost anywhere. Every year about 13 million Americans travel abroad. The most popular vacation periods are during the summer and during the two-week school break on the Christmas and New Year’s holidays. These periods are also the most crowded and generally the most expensive time to travel so people who can adjust their schedules sometimes choose vacation in the autumn. American vacationers often travel by car. Most families have a car, and those who do not have a car can rent one. Cars are usually an economical way to travel, especially for the families. It is also fairly fast and convenient. If tourists want to travel faster, they can fly to their destination and then rent a car to go around when they get there.
