Our tour was the first tour to happen under the schedule to accommodate the elevator replacement. Brett was a great guide and even went on the tour down into the turbine room so he could let his company know of the changes taking place. What a great, relaxing way to tour the site. Brett picked us up in the Hummer, just the 2 of us on the tour, was very informative with details of the area, Boulder City, and the Dam construction, and ended the site visit with a walk on the new bridge for an unbelievable view of the dam. Avoid the group tours, this is the way you want to see Hoover Dam
