We’ve booked a hotel near Essen for the first game then a holiday inn near the airport for the third game, might be on a park bench for the 2nd game
I’ve booked hotels in Dortmund, gelsenkirchen, Frankfurt and Cologne. Jumped gun and booked for round of 16 and last 8 already too. We’re fairly fortunate with planning on our draw. All our games are in and around the same area, avoids the traveling to places like Berlin, Munich etc. If you book in a Dortmund or Cologne you’ll be good for trains around Germany.
