I would like wipe my slate clean and ask you for advice on itinerary planning.
I shall land in Brussels on 2-Sep and depart from Brussels on 22-Sep. What parts of the Schengen-area Europe could I cover in 20 days? I plan to travel by train, fly and do not wish to rent a car. I am an energetic, solo traveler on a first trip to Europe.
Thank you all.
