One way to travel in Europe is on a night train. You travel as you sleep, wake up refreshed and ready for a new day in a new location. There are many night trains that operate all over Europe. Night trains are romantic, safe and fast. If your journey is long enough have a meal onboard and retire to your accommodations for the night. You can use your Euro-pass to pay for the train trip but will have to pay extra for the type of accommodation you prefer. You can choose from a reclining seat to a sleeper cabin.
I took a train from Milan Italy to Munich Germany for Oktoberfest (there were no hotels available in Munich). After a day of drinking beer, we returned to Milan on an overnight train. This was the best since we got to see the scenery on the way up and were able to crash on the way back. Since most of the people onboard were coming from Oktoberfest, the morning coffee was a sight! Doors would open to bleary-eyed passengers in desperate need of a coffee fix. A staff person was on each car and quickly got you your coffee. The return trip stopped at Verona (Shakespeare Romeo and Juliet town).
The overnight train allowed us to experience Oktoberfest in one day. We arrived in Milan refreshed and ready for another day.
