That's an exciting trip to plan! For balancing travel time, I'd suggest grouping countries geographically. For example, focus on Western Europe (France, Belgium, Netherlands) or Central/Eastern Europe (Czech Republic, Austria, Hungary). Trains are usually fantastic for this, and you can often get overnight options to save on accommodation and travel time. Check out sites like Omio or Trainline to compare prices. For budget tips, consider hostels or Airbnb outside the absolute city center. And don't forget to look into the
