Passengers come mostly from Australia and a few from New Zealand. It's a relatively younger crowd than found on some other lines, with an average age of about 45 years old.

The generally easy-going and fun-loving passengers tend to be more budget-focused with value for money more important than luxury.

Although the cruise line is popular across multiple generations, couples and families dominate. It has won accolades for its family-friendly atmosphere with children kept busy by kids' clubs staffed by qualified teachers and childcare workers.

P&O ships do not have formal nights with black tie requirements. Instead, there's usually one or two party nights (check your itinerary), with themes such as the Great Gatsby or the Bianco party, which calls for white clothing.

No. All meals at Waterfront Restaurant, The Pantry, Angelo's and Dragon Lady are included in fares. But all other dining options carry a charge. Drinks (alcoholic and non-alcoholic) are also not included, but dispensing machines for water, tea and coffee in The Pantry are free. In terms of activities, there are plenty of perks -- from the complimentary kids' clubs and comedy shows to cooking demonstrations and pool games. However, shore excursions and P&O Edge activities, such as zip-lining, are an additional expense.

There is a wide range of onboard activities which include fitness classes, cooking demonstrations, mixology classes, live bands, dancing, game shows, table tennis, casinos, cabaret shows, karaoke, deck parties, spa treatments, trivia quizzes, in-cabin movies, shuffleboard, bingo, dance classes, themed nights and parties, talent shows, enrichment lectures and port talks.

P&O Edge is an adventure park that uses the ship as its equipment; for example, abseiling across the bow or climbing the funnel (charges apply).

Also popular are short theme cruises with a focus on food and wine or health and fitness, featuring speakers, presentations and special activities.
