Nautica, who joined the Oceania Cruises fleet in 2005 , boasts a new feature: private cabanas.

Eight cabanas, each with a double Balinese sun bed surrounded by white curtains, will set guests back $50 on port days and $100 on sea days. They'' alsoi get some extra treats thrown in.

"They're very sexy," says an Oceania spokesman.

Passengers may order from the Waves Grill menu, and treats delivered throughout the day include iced towel wraps, fruit skewers, ice cream and afternoon tea.

Those who book a full-cruise cabana package get extras such as a complimentary 10-minute chair massage, a 25 per cent discount on Oceania Spa by Mandara services performed in the cabana on port days, and a cabana bag with sun care products, visors, towels and other items.
