Where will 2018 take you?

Happy New Year to you all! We met up with some friends recently who are embarking on 'an alphabet tour' of the world - i.e. they made a list of countries they'd visited according to the alphabet and are now visiting the ones they haven't been to. I thought this was a great idea and decided to compile a list myself. I have been very fortunate to travel as much as I have (and there are still are a number of countries that I still haven't seen) but my alphabet tour would include any countries starting with the following letters: K, O and Y. Which countries would be on your list?
