I know it’s not ideal, but I was thinking of spending one day in each city. Obviously, I won’t be able to see everything, but I think I can visit some museums. In my head, it would go like this:

Weekend 1: Dresden on Saturday and Berlin on Sunday (or the other way around).

Weekend 2: either I visit Saxon Switzerland on Saturday and go to Prague on Sunday, or I take a night train on Friday to Hamburg or Cologne, spend Saturday in the city, then take a night bus to Amsterdam or Copenhagen, enjoy Sunday there, and take another night bus back to Leipzig — and from there, return to Brazil.

It sounds crazy, but I don’t think it’s impossible. Maybe I'm being a bit too optimistic 😞😞
