I booked the Hoover Dam Tour for my boyfriend's birthday. Everything was going smoothly from the pick up to the drive out to the dam. I loved our bus driver he was very loquacious and good humored even though the group wasn't responsive. We did the early morning tour so that might have something to do with the lack of participation. The driver tried to engage in a lot of call and response only he didn't get many replies but again he was still fun. Unfortunately and due to no fault of the company our tour was cut short and we didn't get to see The Mike O'Callaghan- Pat Tillman Memorial Bridge because while we were at the dam it was evacuated because of an emergency. I'm still unsure about the details it happened very sudden but a man in an armored vehicle blocked several lanes on the bridge and police thought he was armed. Thankfully he was apprehended without incident but of course the situation was frightening. Nothing happened but the tour was cut short I completely understand though with all that has happened in the world it's better to be safe than sorry. If I make another trip to Vegas I would use this company again after all I did enjoy the portion of the tour I received.
