We are currently still waiting on this bus at 5pm which was the estimated time we were supposed to be back to our hotel. The sites at the Hoover Dam were amazing, but this company clearly doesn't understand the definition of an "express" trip. We were told to be back on the bus at 4:15 which the driver said if we all made it back earlier than that, that we could make it back for happy hour. The driver never mentioned that after us getting on the bus on time that we would the. Have to wait another 25 to 30 minutes for the people that purchased a helicopter ride to take their ride. For people that are on a time schedule do not use this company as you will arrive back to your hotel well past your estimated time. You will basically be punished for not purchasing a helicopter ride. Not leaving Vegas on a good note that's for sure.
