Excellent tour! Our guide, Catherine, showed up right on time. She was knowledgeable and happy to answer any questions we had. She got us in without waiting in any lines. She distributed headsets which allowed us to hear her without having to crowd around her. There was only one other couple on the tour so it was like having a private tour for ourselves. Versailles is a must see and this tour was definitely the way to go. I would highly recommend it.
