Please GO on this tour! Our guide, Tomasz, was fantastic - he does not need to improve a single thing. He has such a pleasant personality and is brilliant in his knowledge of history and all things Krakow/Auschwitz Birkenau. His English is excellent. The drive went by quickly as we enjoyed conversation with Tomasz, and his insights prepared us for the sobering tour ahead. A different guide took us through the camps (as required by Auschwitz) and we each had an earpiece for most of the tour, which really made it easy to hear. (Birkenau does not offer earpieces and we wished it were possible.) School children in Poland are required to visit the camps --- to me it seems that residents of the world should be required as well. This staggering piece of world history must be understood by all. I highly recommend this tour.
