Hello all. We are taking a family trip in August to Prague, Krakow, and Berlin (in that order). We know these are all lovely cities, but we would like to break up the trip with a 1 or 2 night stay at a luxury resort on the general path from Krakow to Berlin, or Prague to Krakow. We would love to be on a river or lake. (we will have a rental car). I've thought about Dresden.
I know it's possible that no such places exist. I've also posted this on the Berlin forum.
Any and all ideas are welcome!
