It's the best idea.I dont know who first thought about it ,but its genius. Its not only about travelling in low cost , you get to meet local people from the country you re visiting .You come in close touch with their culture ,their everyday life ,an opprotunity for a big insight . For sure noone can show you around better or give you hints ,than someone that loves their place .
