I am planning a trip to the Salt Mines in October - will buy tickets for the 17:25 English tour, and take the bus back to Krakow (the bus stops just outside of our hotel, Red Brick Apartments). Can someone tell me realistically how long the tour will take? I have heard 2 hrs, 2.5 hrs, and 3 full hours. We do not intend on going to the museum after, and will head straight for the bus back. I wanted to know to see what time I should realistically make dinner reservations for that night! Thanks!
