The majority of passengers on Norwegian Jade's Europe-based itineraries are from the U.K. The rest are a mixture of people from Australia, France, Spain, North America, Mexico, Japan and Korea. The average age hovers around 55, with the largest number of passengers in the 55 to 70 range. During summer months, expect a sizable influx in families. Caribbean itineraries draw a younger, more American passenger base, including families.

Norwegian Jade's dress code is relaxed, with many people adopting a casual style -- bathing suits, T-shirts, shorts and jeans -- during the day. At night, passengers tend to dress smartly but comfortably, with most opting for slacks and blouses or collared shirts. Norwegian ships don't have formal nights, but each sailing offers at least one "Dress Up or Not Night," on which passengers can dress up if they want to. Few on our Caribbean sailing chose to do so; Europe voyages tend to be a bit dressier.

Norwegian charges a "service fee" of $13.99 per person, per day, for passengers booked in standard cabins and mini-suites. Those in suites are charged $16.99 per person, per day. Cruisers wishing to adjust or remove the charges must fill out a form post-cruise to request a refund.

Norwegian recommends that suite passengers who use butler and concierge services tip according to the level of service rendered.

An 18 percent gratuity will be added to all bar purchases and services in the spa and salon.
