I didn't realise until I went that most of the old, the women and the children never made the site huts, they were walked down the line straight to bunker one and bunker two for "showering". On their "best" day they murdered around 11000 human beings. utterly incomprehensible....
Yes mate, I think it is wheelchair friendly, though its best to book through one of the guided tours. Their English is superb, everywhere you go, and food and drink are so cheap its untrue. A carrier bag full of delicious bakery goods to see us through the day was about eight quid. In the evening a couple of steaks and a bottle of wine is under £40 if you go some where quiet. Accomodation in one of the old city apartments is cheap and beautiful. And the old part of Krakow, with the square and everything, is like going back in time fifty or sixty years here and visiting London. its a stunning city.
The two camps are definitely somewhere everyone should visit..
