Hotelito DesconocidoItalian designer Marcello Murzilli's upscale palafitos (thatched-roof beach bungalows) on the Pacific resemble those in a traditional fishing village.

The hotel is solar powered, and almost everything in the rooms, at the spa, and on your plate (marlin tostadas, homemade guacamole) is local and organic. Playón de Mismaloya, from $312 for a double (includes breakfast).
