     Americans like to travel on vacations.  Today  more  and  more  travellers  in  the  United States are

spending nights at small houses or inns instead of hotels. They get a room for the night and the breakfast

for the next morning.

     Rooms  for  the  night  in  private  homes  with  breakfast  places have become popular in the United

States.   Many  of   these  America's  bed - and - breakfast  places  are  old  historic  buildings.    Some

bed - and - breakfast  inns  have only  a  few rooms.  Others are much larger. Some inns do not provide

telephones or televisions in the rooms while 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 area

and the interesting places to visit. Many vacationists say they enjoy the chance to meet local families.
