Worst bus trip! Purchased tickets at Treasure Island and waited over 40 minutes for bus to come. When it arrived, it was almost full and only a few seats in the bottom. As we went to each stop, more people came in and they decided have people stand in the aisle. A bus tour with people standing blocks the views and is not safe. It was suppose to be an "on-off" tour, but you didn't want to get off because it would be hours for the next bus to come. Finally they arrived at Circus Circus and parked on the other side of the parking lot, away from their bus stop and told everyone to get off and walk over to bus stop see where and when the next bus would be because neither the driver or tour guide knew.
