The Hotel Plaza Athénée Paris has remade two of its rooms to look like life-size Barbie dream-houses. Targetted at the children of guests, suitable for ages three and up. They also supply a "special girlie gift" ("designed by Barbie!") to each guest. Costs a mere €1,600 per night (connecting parents' room is an additional €2,500/night).
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
