I pre-booked online my day tour to Auschwitz-Birkenau and The “Wieliczka” Salt Mine on Viator before arriving in Poland. It cost AUD $121.11 and that included lunch, hotel pick up and drop off. Krakow Shuttle Tours was the company that handled the tour. All communication was done via e-mail. On the day of the tour, the driver/guide was extremely prompt for my hotel pick up, on the dot at 07:30. Vehicle was a Mercedes Benz mini bus, comfortable with a total of 8 passengers including myself.
