Why dont many hotels have a 13th floor?
Many consider 13 to be an unlucky number. A lot of elevators,
especially in America, don't have a 13th floor and skip right over
to 14. It doesn't mean that you're missing a floor, because
technically the 14th is the 13th, just not called the 13th because
13th is unlucky (does "Friday the 13th" ring a bell?)
