Allow me to reccomend Colditz. It's a long way east but well worth it. Stood on one balcony we were shown the evidence of four escape attempts:
The bell tower above and to one side was where the French started a tunnel. This came down the tower and under the church floor. The hole the Germans dug to try and fill it in are still open and you can look down and see where they started to go horizontally, cutting 12" oak beams. The were betrayed and caught when they'd started on the last wall.
The ridge above is where the British were building a glider.
The actual balcony was part of the "Franz Josef" escape where a prisoner disguised as the guard sergeant went round dismissing the other guards.
Up an to the left is a round stairway. A Canadian Olympic champion noticed that on the spiral stairs the middle man couldn't be seen. Causing delays they opened the sixth floor window and he jumped! Dropping probably 10 feet at a time from floor to floor, catching the window bars he made it to the ground only to break his ankle on the last drop.
Even the guide (they use local students) had a story. Her grandmother was working in a field and was offered cigarettes for food by two six foot chaps wearing RAF greatcoats. On the basis that you couldn't hide two huge Australians they'd decided to simply walk as far as they could before they got caught!
The museum and tour are fantastic. The town is very nice with good food and beer. The only place to avoid is the campsite, but there are load of B&B's.
I'd love to join you, but I doubt Karen would be happy if I invited you all on the honeymoon
