Our tour had a little hiccup at first, however our Tour Guide, Bil C. made arrangements quickly and we were on our way. We had 8 individuals on the private tour. We had multiple viewing points of Hoover Dam, including the 2 hr stop at the Dam. The 2 hrs was plenty of time to take the generator tour, along with the Original Exhibit building, New Visitor bldg and the Dam itself. I would highly recommend booking the VIP tour. Bil C. was gave us history of Las Vegas, Hoover Dam and the towns along our path to the Dam. When we were finished, we could move on to next stop, without having to wait for an entire bus of people. Thanks Bil C for the great tour !!!
