A visitor is a traveller who takes a trip to a destination outside his or her usual environment, for less than a year, for business, leisure or other personal purpose e.g. education or medical care, other than to be employed by a resident entity in the place visited. Visitors comprise tourists and excursionists. An excursionist is different from a tourist in terms of duration of stay at the destination which is less than 24 hours e.g. visitors from the cruise ships.
