Parking ticket Berlin how can i pay it online ?

If you are not going back to Berlin, why would you worry?

It won't cost a million. But it will cost a lot. And it depends on where you plan on travelling, which you don't actually mention. Why don't you put your savings into some kind of deposit savings account, which gives you interest on those savings? It would make more sense. Oh, and at 17 you won't be allowed to buy alcohol in most places, and you will probably find it difficult to find accommodation also, as most businesses don't take on unaccompanied minors as customers. If you are thinking of taking those train passes, be sure to read the small print very carefully and see what it actually covers and whether or not you will need to play extra on some services. If you're only doing 4 countries, I think that getting a pass for 24 countries is a bit excessive.
