Most of us like travelling around the world. The most necessary "product" whenever you travel is the accommodation. There are several online hotel booking engines, like booking.com, lastminute.com, expedia.com and other well known sites.
So someone who needs accommodation visits those sites and tries to find the best offer. This process needs a lot of time, but there is also another way to do it. There is at least one hotels' search engine that is used to search to several sites at once.
The site that I know is the http://www.hotelscombined.com/. This sites simply returns results from several sites and lets the user choose!
