Hello George Fleetwood,
Thank you for your review!
We would like to remind that this is free tour and many of the tourists treat it not seriously and in many cases they are not shown. And hence, sometimes this totally waste of time for guides. So in order prevent this we send confirmation e-mails to the tourists and are due to receive confirmation not later than 11 pm on the previous day. Our working hours, as you also can see on our tripadvisor profile is 10 am to 11 pm. Yes, it was too late, because at this early time when everyone sleeps, we could not organize tour. Moreover, you are the only one who have signed up that day. And the guide also was waiting until 11 pm on the previous day, so we notified him. But your reply came too late...
