Where are they?
The funny thing about traveling is that there's new people to meet everywhere. The best place to meet people is, obviously, at your hostel but don't limit yourself to just that. You're a tourist in a strange land. You're mysterious and adventurous and you'd be amazed at how many people want to hear your story. Go on a pub crawl, take a tour, travel by train, download a dating app, do a little couch surfing - there's so many ways to meet new people.
