Travelling to Poland in winter by road - some insights & best options to Munich from Warsaw

Hello all, needed information

A) Some insights on travelling to Poland by car from Germany DURING WINTER. Has anybody done that ? How safe is it? How good are the roads? Your suggestions? experiences? What are the should be's or should not be's?

B) Travelling to Regensberg via Munich (or only to Munich) - Cheap travel options by rail, flight or share cars. Checked deutsche Bahn, any other ?

Thanks in advance !!!

it depends on where you're heading; if you go to Warsaw I advise to go through Berlin - Poznan - Warsaw --> you'll drive by highway almost all the way

thanks, what about the mode of transport from warsaw to munich ? where to look into?

You can fly (direct) for about EUR 130. I'd certainly do that.

cheaper options any ?

As far as I know there are no cheap airlines operating that route, so the cheapest way will be bus. Rail would probably be not much less than plane.

yeah, sounds about right, thanks.
