We are a group of 5 (slight possibility of 6) siblings/cousins on a "roots" trip to Poland. We have booked 5 nights in Łódź, which will give us 4 full days to explore Łódź. The family originated in Przedbórz, so we want a day trip there. And some of us are also interested in trips to Chełmno and Auschwitz. So, we are thinking one day full day exploring Łódź, then day trips (with a van/driver/guide) to the other 3 locations. Chełmno is probably a half day trip, but the others will be full days.
Any pointers to drivers/guides originating in Łódź?
