Jersey - London City Airport - Frankfurt on the 13th.
Train to Koblenz, based there Airbnb for 15 nights, early morning train to Munich day of game.
Took a gamble with the location we booked months ago, paid off as Cologne and Stuttgart within easy train commute.
In between Scotland games probably train it to a couple of other host city’s ( Düsseldorf, Frankfurt ) for a day in the fan zones watching other games.
