This is how you travel to any country for free. Now I'm going to Hawaii. So I downloaded the couch surfing app and I started requesting to people in the days that I want to stay in their home. One girl, Pauline, accepted to host me. After landing in Hawaii, I went to meet Pauline and she was the best host ever. She took me to the beach and she showed me the best spots in the city. In the night, she cooked food and I slept on her couch. By the way, this is not an ad. The couch surfing is much more than free traveling. It's the best way to see the culture of the place that you are visiting while making new friends.
