P&O Cruises managing director Carol Marlow said: “This is the first time we’ve run a specific Caribbean, Central and South America fly-cruise programme on Adonia and with three maiden calls for P&O Cruises, it’s a very exciting, must-do trip. Passengers can enjoy a much more authentic Caribbean experience visiting tiny islands which larger ships cannot visit. They can head off-the-beaten track in Central and South America to discover banana coasts, rainforests and amazing ecosystems with a huge array of animals and exotic birds.”
