Instead of being cliche and giving stars or thumbs up when considering things like the people, culture, food, sites, history or scenery, I've decided to rank places on something much more useful: the toilets.
I have a more granular level of detail for cities I've visited, if you may be interested, but here are my thoughts on some major regions. I'm pretty sure that even if I make it around the world, North America will be the best. (Though at country level, I am guessing Japan would top them all by a long shot based on what I've heard).
