Of all the cruise lines that I have been on, NCL is the most informal. The casual nature of NCL is due to their "Freestyle" theme. Freestyle cruising allows the passengers to choose when and where they want to dine on the ship. You don't have to be regimented to a set dinner time nor be banished to the buffet if you don't want to participate in the formal evenings. As a result, the passengers don't have to bring as many outfits, which helps them to scale back on their luggage. In a sense, NCL has gone green!
