Day 5 of our family European road trip takes us into the Netherlands for a wonderfully slow day at De Ullingse Bergen near Sint Anthonis. After abandoning our plans for Aachen, we discover one of the best family campsites and self-catering chalets we've stayed in, complete with pools, go-karts, fresh croissants and a little taste of Dutch childhood independence. Sometimes the unplanned stops are the best ones!
