Travelling to Germany

We booked the 2: 50 flight from Mumbai to Frankfurt and then a connecting flight to Hannover. We were to then board one of the regional trains to Braunschweig. Three of us reached the airport from Campus around 11. I had made a lot of plans on how to use the onboard entertainment to its fullest - watch at least 3 movies - one of them the House of Gucci. But I fell asleep just 10 minutes into the movie; woke up to see the murder of Gucci done and breakfast being served on the flight. We reached Hannover at around 8 40 local time and we had to catch our next flight that was to depart at 9:20. My friend and I reached the boarding gate well before but 3 of us got delayed because of a long queue at the security check-in at Hannover. The two of us boarded the flight and reached Frankfurt. We then took an ICE train from Hannover to Braunschweig (missed a train in between due to a delay) and reached Braunschweig at around 12 pm. We then hopped on a bus to Hamburger Straube as direct...
