I am a 31 year old male flying to Berlin in 3 months by myself, staying for 10 nights. I've flown to Canada and other U.S. states but never out of the continent. I have my passport and plan on finding a hostel or apartment to rent while over there, then taking the train to Prague for the last half of the trip. Am I way underthinking this? Are there things I need to know or do really before I go or will I be fine just asking people once I am there and trying to plan out the public transportation/train system? I have a rough list of things I want to do/see there so that's not my concern, I am just wondering if I need to be worried about navigating the country/train alone without a lot of prior knowledge. Can someone put my mind at ease? Thanks!
