These are the world's top 20 trending destinations, according to Airbnb - and you've never heard of most

Earlier this month, travel rental company Airbnb analyzed its 2017 and upcoming 2018 booking data to reveal its forecasts for next year's hot spot destinations.

Airbnb compiled a list of places where bookings have doubled, tripled, or more, from the first half of 2017 to the first half of 2018.

While some destinations like Hanoi, Vietnam, and the Greek island of Mykonos have long been vacation favorites, other places, like the small Brazilian beach town of Matinhos, will be new to even the most seasoned of travelers.

Take a look below at the top destinations to visit next year.
