Traveling requires money and time, but to be honest you mainly will need time.
You can spleep in somebody house for free or simply having a drink to meep up and discover the place with local people.
When you are traveling, there are some places hidden for tourists, so this option will bring you to the core of the place where you are at any time.
Everybody is trully friendly and you will have to decide wich of them match with you based on the profile.
There is not more excuses to enjoy your time even in your own or with somebody else.
In my personal experience, I came back home with extra friends in my pocket 😉
A trully open eyes experience of kindness.
