The Verdict

Carnival is about casual, American-style fun cruising at a fair price. The ships carry thousands of young — or young at heart — cruisers who can only be described as down to Earth. Carnival doesn't try to be fancy, though its newest ships are surprisingly nice. (Our advice? If you're looking at an older ship, be sure to choose one that's been updated with the latest amenities.)

Vs.

Tradition reigns on Princess cruise ships, which attract slightly older American, British, and international passengers looking for a customary cruise with some contemporary updates. The classic experience may read as old-fashioned, even sedate, to some cruisers, but others will love the combination of activities and opportunity for rest. Summertime and holiday periods attract families, but these ships are mostly designed with grown-ups in mind.
