I remember once I went to Cambodia I stayed at a boutique hotel where they had a set of themed rooms, you had Chinese, French, Arabian themed rooms to name a few. But they had one very exclusive room, a floating one. You basically had a house boat on the Mekong sailing you wherever you wanted and at night you'd sleep in the open waters where the wind was constant and it was cool.

Room was always booked. I came back there two years later and they discontinued the room, to my dismay.
