Thank you for your review, although we are of course sorry to read that you were disappointed with your tour. There was indeed a road race that day, the information that we had received from the prefecture of police indicated that the meeting point would be accessible on foot, which is how we always access it, and that the road would just be closed to traffic. However as you saw on the day this was not the case, it was blocked off and we are sorry about that. We called all the guests on the tour to inform them of a new meeting point by the tower, and our coordination team and the guide moved to the new spot that was easily accessible. It may have taken a little longer to contact us on the day as we were on the phones calling the guests. The tour started a bit late as we wanted to ensure we got everybody, which we are happy to say we did except for one couple who did not come, and of course the guide took care to do the full length tour so you did not miss anything.
We all have to go through security checks at the tower and there is no skip the line privilege there, but our guides are there not only to tell you about the tower and her history, but to help smooth your passage through the various checks and lines.
We very much hope that you enjoyed your visit despite the issues at the start, and that you had a great time here in Paris.
