We took the mini Hoover dam tour. The tour was good but it wasn't necessary to take us off of the bus we were picked up on, corral us into a sales presentation to upgrade when we had prepaid, and them load us into a new bus. Wasted 45 minutes.  On the return trip the drop off was horrible!!!! And they didn't drop us back at Ceasers Palace but drove around for an hour then dropped us off at ballys in the rain!!!! We were told we would be back by 1:15. We got back at 3:00.
