I've cruised with Carnival (1), NCL (1), Royal Caribbean/Celebrity (45 days at sea), and one European Rive Cruise on AMA Waterways. I LOVE cruising. So far my favorite cruise line is Royal Caribbean because of their innovative ships, amount of things to do, the Royal Promenade (love it!) and there's a level of fun but it's not the "everyone get wasted and party" like Carnival was. That was in 1987 when I took the Carnival Celebration and I was in that mode myself back then.
