Postbulletin.com: Rochester, MN: "There are many reasons why the Caribbean is and has been for years the No. 1 cruising destination in the world.
The primary reason, of course, is the region's warm climate. Year-round cruising is possible there, and that's not in the cards for many other also-popular but more seasonal itineraries, such as the Mediterranean, the Baltic, Alaska, the British Isles, and major areas in South America.
The price is usually right for a Caribbean cruise, too. Because cruising is popular all year, there is a plethora of competitive pricing among the 25 to 30 ships that ply the warm waters of the region."
