In Colorado, where it is legal to smoke cannabis, a hotel chose to stencil the number 420 on a door, rather than deal with the hassle of replacing an often-stolen placard.
Another hotel decided to just avoid the number altogether, skipping from 419 to 421.

While the practice of avoiding the number 420 appears to be a recent trend, hotels have often chosen to skip the number 13 when labelling floors or rooms.
In Chinese superstitions, the number four is considered very unlucky, due to its similarity in pronunciation to the word for death.
As a result, fourth floors are often omitted in hotels and high rise buildings in some East Asian cultures.
