Tango is truly a world-wide dance, and many people find that Tango festivals are the main motivation for them to hop on a plane. Few social gatherings are as open to meeting new people as are milongas. Before you go somewhere, check the web to see if there's a tango club in your destination. Taking a class or going to a milonga can be a great way to meet new friends in a city you might not know anything about.
