Ever wanted to travel the world for free? You're in luck, because TourRadar and Intrepid Travel are teaming up to pick two people to do just that. The only catches are, you have to travel with a stranger and you won't know where you'll be going. TourRadar is doing a new campaign called "Tour the World" that will have two participants who are strangers travel the world and tour five different countries, while being filmed for the company's social media accounts and marketing videos. Oh, and the two strangers won't find out where they're going until they are selected.
