GetYourGuide.com is a website that offers international tours and activities for tourists. The site looked at the reviews left by residents of 50 countries on their site, and here's what the found.

South Korea came out on top as the country with the least happy travellers - 18.5% of its reviews ranked as just one or two star.

Other countries full of complaints were Mexico, Columbia, Peru and Argentina.

But its not all bad news because tourists from other countries were much more easy going.

The long-suffering Czech Republic placed first on this list with 92.3% positive reviews, followed by resilient Russia, Poland and Malta. America finished outside the top 10 with 83% positive reviews.
