A week into her Caribbean voyage, the Star Princess drops anchor at Amber Cove in the Dominican Republic. On board, the crew are throwing themselves into St Patrick's Day, with cruise director Dan and his team transforming the ship's Irish pub into party central. Massage therapist Charlotte has her eye on a bigger prize than shamrocks though: talking her way into DJing the guests' silent disco, currently the preserve of resident DJ Will. It's a chance to show off a talent she's kept hidden below deck.
