Americans like to travel on their yearly holiday.Today，more and more travelers in the United States are spending nights at small houses 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 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.Some inns do not provide telephones or televisions in the rooms，others do.

Staying at a bed-and-breakfast inn is much different from staying at a hotel.Usually the cost is much less.Staying at an inn is almost like visiting someone’s home.The owners are glad to tell about the areas and the interesting places to visit.Many vacationers say that they enjoy the chance to meet local families.
