We left the car and mum at Konstanz and embarked upon the train travel leg of the tour. No one in Switzerland has asked to see our passports. We have decided it is just an extension of germany. 74% of people in Switzerland have german as their mother tongue, whereas only 21% have french. English does not ever register. The 3rd language is Italian and the fourth official lnguage is Romanish. (Based on Latin). Our hotel is on the river. Very nice
