As college students, my three friends and I wanted to be able to explore the city on a budget. This bus company allowed us to be able to explore all different parts of the city while always having a reliable transportation source to go back to. However, we wanted the live guided tour the whole time, and only 1/3 to 1/2 of the buses seemed to have a live tour guide, and there was no schedule we could find that told us when live and recorded bus tours would stop at which locations. If a schedule like that were to have been published and given to us, this would be a 5 star "no reservation whatsoever" review. Thanks, though, for a wonderful experience! Ash was a great tour guide.
