We had a tour booked for 2:00pm. We got there literally at 2:03pm because of construction in the area and they wouldn't let us join because we were late. I said to the lady that were were only a few minutes late and that I was surprised they wouldn't let us join, her response was "Well you're late so that's not our fault" - I was absolutely shocked by her response. Very unprofessional. Anyways they didn't let us on. So don't be late!
