Are you trying to be a nomad? Or are you just trying to be an expat? That is, say you decide Ibiza is the best place. How long are you going to be there? Five or ten years? Or are you going to move on to Crete after three months?

If you're going to be there for several years, then yes, look at schools. But if you're only going to be there for three months, then I strongly suggest that you think again about what you're going to be doing to your kids. Switching schools every three months is horrible for your kids. It disrupts their education as well as their social life.

So maybe a bigger question: How much are you factoring your childrens' well-being into your planning?
