Dear Thomas,
I am very sorry about the unsatisfactory experience. On the 14th of July we had over 3 evening tours that were scheduled and departed at 8:30 and everyone has made it on time. We have tried to find a solution to this problem when you were late for the tour and we offered the following day, however you should also remember that now post covid everyone wants to travel so the availability is very limited, yet we managed to find an availability for you.
