Hello Glenn, I am sorry the experience didn't go as you expected. The tour guide waits INSIDE the bar, at the entrance, next to a table with our logo and our flyers. The personnel of the bar is informed of the event and they are happy to point the guests in the right direction in case they can't find the guide. It's true that on that night there was a large group of students who were partying at the same bar so maybe this caused some misunderstanding. It is for situations like this that we leave our phone number for you to use in case you are lost and we haven't received any message or call from you. You only sent us a message on viator after one hour the tour had started, saying you couldn't find the group. I am sorry to hear that you waited for one hour without trying to contact us and without checking inside. We'll make sure to write it more clearly in the tickets to avoid this situation to happen again in the future. I wish you a pleasant stay in Paris!
