Next time you're hitting the road for a conference, exhibition or just a few days away here's a cool Facebook application showing users where everyone has stayed in the past.
The HRS friends app, which is in beta, shows users a map of where their Facebook friends live or where they have recently checked-in using the social network.
The app also enables users to view available hotels in the area where friends or people within their group live or search for properties with those 'liked' by friends highlighted in the results.
Facebook check-ins and data from Foursquare are also used to create a heatmap of areas of interest in a city enabling travellers to draw on friends' experiences before finalising plans.
The service also includes a group trip function for users to create and share plans.
The HRS friends is available in several languages including English, German, French and Russian.
