We've cruised several times on both Royal Caribbean and Carnival. To this day, I don't know why so many people think of Carnival as a "party ship". Makes it sound like Mardi Gras, 24/7. Maybe it's because the Carnival ships tend to have more poolside activities than RCCL. If you go to this website:Cruise Ship Virtual Tours | Cruise Videos | Carnival Cruise Lines
, you can take a virtual tour of the ship and it will give you some idea of what to expect.
