A few clicks is all it takes these days to sort the hotel for your holiday or business trip. Why call the hotel directly when you can use online portals like Booking.com, Expedia and HRS?

But in fact, it could be a good idea to look more closely before you click. Online booking services don't come for free - and it's usually the consumer who ends up paying.
