Friends of mine made the trip with a similar sounding arrangement as suggested by Neil. It has to be done. No cameras mind...well, not inside the museum places.
My wife visited Dachau several years ago on a school trip and has never forgotten the experience. There was a party of German school kids on the trip who were in jaw-dropped bewilderment for the whole experience.
It's Holocaust day today - by coincidence. To be frank it isn't a day that really means a great deal to me. I feel detached from the Holocaust in a way I cannot explain. Ethnic perhaps, but more because I can't empathise. I guess I have to make the trip.
