A substantial proprtion of people are travelling alone and want to strike up a conversation with you, even though they're headed off somewhee else the next day.

Youmight not even need to find a bar: the popular sights and major cities of the world are full of hostels geared towards encouraging their guests to meet fellow travellers (some more overtly hedonistic than others). They're easy enough to find in travel guides and hostel booking websites

You'll also be surprised just how many local people speak English in the rest of the world, particulary when affiliated with the tourist trade (Latin America being something of an exception, but basic Spanish isn't the most difficult language for an English speaker to learn.)
