Rügen? Sylt? Other points north?

I’ve got some more time off coming up (I know, I know).

Who’s been Up Nort’ in Germany and can provide some inspiration? Think Eastertime. I’ve been curious about the ports of Lübeck and Kiel for many years. Not opposed to renting a car and exploring that way, but I tend toward Deutsche Bahn travel when I can get it.

All suggestions welcome!
