There are 196 countries in the world, but most travellers will only see a small fraction of them in their lifetime. It doesn't have to be this way. While international travel can be more expensive than domestic travel, a bit of research, timing and luck can help lower the cost of trips abroad, meaning your suitcase doesn't have to collect dust this year.

Trivago.ca decided to use this feedback to find out just which cities around the world are keeping tourists the happiest.
