This sounds like a real HOOT! If I had the spare cash, this would be my idea of a great holiday. But then again, I already live in a South Pacific paradise -- the sort of place people like to vacation at. A WW-II POW camp for a week "just for fun" sounds like a fantastic change of pace, and a nifty opportunity to step back thru time and experience History.
High on my bucket-list! That and the Nijmegen march.
