Holidays if you've got a big bonus: Song Saa Private Island, Koh Rong Islands, Cambodia
Recommended by: Mr. & Mrs. Smith, who say:
Get away from it all at one of the most beautiful new hotels in the world. Ultra private and gratifyingly luxurious, this is an eco-luxe escape spread over a pair of pristine isles, with thatch and stone villas dotted among the jungle canopy or lolling above the sea. Being green-minded has never been so glamorous.
Cost: Rooms from £1,090
