Carnival Sensation's onboard atmosphere is one of endless fun and expectant excitement. Everyone is trying to pack in as much amusement and downtime as they possibly can in four or five days (the ship is dedicated to short cruise itineraries). It's not frantic, just fun. And everyone's got everyone else's back, whether it's enthusiastically dancing in the aisles during nightly karaoke or loudly cheering on cruisers who have volunteered to participate in any number of interactive activities -- it's hard to feel embarrassed onstage when the entire audience is hootin' and hollerin' for you.
