Visitors' Pass

Some cruise ships permit passengers to invite guests on board prior to sailing, although most cruise lines prohibit all but paying passengers for reasons of security and insurance liability. Cruise companies that allow visitors usually require that you obtain passes several weeks in advance; call the lines for policies and procedures.

Most ships do not allow visitors while the ship is docked in a port of call. If you meet a friend on shore, you likely won't be able to invite him or her back to your stateroom.
