I was initially not interested in going up in the tower because of the long lines and wait times. However, my travel companions wanted to go so at the last minute we found a "skip the line tour" starting at 10.00 and it was fabulous. Hannah was our guide and she was able to provide wonderful and interesting information on the tower and Paris. I would have regretted missing this if my friends would not have found this thru Viator. Yes, even in September the lines were long but guess what? not for us, we just trapsed right thru. Hannah was great and we loved the tour.
