We're looking for a 2020 summer family holiday outside the UK, for a family including two teens. Camping and other uncomfortable accommodation is ruled out, as is any kind of expensive train travel (Eurostar). We need somewhere with good travel connections (to it and within it). In the past, when our budget was slightly higher, we did Amsterdam, the Belgian coast, Berlin, the Black Forest....Does anyone have any other good suggestions for what looks like being our last 'abroad' whole-family holiday?
