We Purchased this tour and exited at the zoo to spend a couple of hours. When ready to continue our tour, we walked towards our bus stop as the bus was approaching, we were surprised to see that the driver did not stop. She rang her bell twice to announce a stop, passed the pickup point and stopped at the stop sign, then rang her bell to leave. If we waited for the next bus, it would have been 1 more hour. We took the light rail back into town. After talking with sales lady, we receive a credit for half of the tour and an apology. But I am still upset that we never got to see the second half of the tour. This could have been a great tour of the city, but this driver failed us.
