Americans like to travel on their yearly holiday. Today, more and more travelers in the United States are spending nights at small house or inns(客栈)instead of hotels. They get a room for the night and the breakfast the next morning.

Rooms for the night in private(私人的)homes with breakfast have been popular with travelers in Europe for many years. In the past five to ten years, these bed-and-breakfast places have become popular in the United States. Many of these America’s bed-and-breakfast inns have only a few rooms; others are much larger.
