It used to be that Carnival saw the future as shorter cruises. They still do, but they've also discovered there's a market out there for cruises longer than seven or eight days. A couple of years ago they created the Carnival Journeys concept just for some specific situations.
The program has been growing year by year, and Carnival just announced the 2018-2019 winter program and next year it grows to 13 of the longer (12- to 14-day) cruises from a wide variety of ports.
Details appeared in the February 21 edition of Cruise News Daily.
