You can pay 1000s a night or just 10s for a houseboat in your destination of choice – it all depends on where you are and what sort of vessel you're looking at. Opulent boats with rooms to rival the top hotel resorts are available, and so are yachts with on-board skippers. They tend to cost the most, while cheap, inexpensive options are also available in the form of rustic barges, Keralan skiffs, and the like.
