Guided tour with shared transportation
If you're 1-3 persons and don't want to spend extra money for convenience of private transportation this option should be great opportunity for you
For only 200PLN per person you can round transporation to Auschwitz and Birkenau, plus tickets for guided group tour around Camps with English speaking guide.
If booked early enough there is an option of hotel pick up, closer to the date departure only from meeting points located at convenient distance from center of Old Town
Please note that at this option pick up time is not fixed and you will be informed about it day before tour. If you prefer to have certain schedule of day organized in advance I recommend to book private transportation which is more but pick up time won't change
