Purchased my tickets for August 13, 2016 tour. We picked up the bus at 10:30am at The Tropicana hotel with no issues. Although tour guide seemed a bit irritated, he did share some good information to our short first stop. We "hopped off" to go to Madame Tussauds as our first stop. We then "hopped on" at TI to go back to hotel to drop off what we purchased at MT. On this particular ride, the female tour guide was absolutely horrible. She was either drunk or under the influence of something. This lady was actually stumbling and tripping on herself. She shared absolutely no useful information about beautiful Las Vegas. She was very offensive to us and to the two other people on the bus. At the next stop, two kids and their parents hopped on and she was such a lush to this kids and their father. Again, she gave absolutely no useful information but rather proceeded to just talk about herself and other people on the bus. One minute she was from California and the next minute she was from New York. She was talking nothing but nonsense which at time was so comical because we felt so bad that she was making such a fool of herself. To top it off, neither of the two busses had air conditioning, we chose to not continue with this tour and "hopped off" at the Excalibur. We missed out on going to the beautiful downtown Las Vegas, Las Vegas sign, Pawn Star shop and the Mob Museum which were the stops we had planned. This was by far the worst experience in Las Vegas and would never recommend the Big Bus tour Las Vegas to anyone!!!
