This tour has buses with plug in headphones, which cut in and out and was sometimes not understandable, even when loud enough. The good is that there are multiple language options. Some other cities have live tour guide on a microphone. Better facts and figures and audible conditions. Would not recommend this option on a Saturday the day we toured. Traffic in Sydney on Saturday is crazy, everybody is out, it is such a great city. Only problem is there is not time to hop off and back on, cause buses are too crowded and you likely won't get all the way around. I'd do this over two days, during weekdays, instead.
Well worth doing - always the best way to start a visit to any city. Would have been helpful if we had been aware that the trip to Bondi only goes from Central Station - we did a complete loop of the city then had to do half of it again to get the Bondi bus. Best to do the Bondi trip once you get to Central Station then the rest of the city trip once you get back there.
Commentary really good, everyone very friendly.
This is the best way to introduce a new visitor to Sydney. Very easy to learn where the sights and points of interest are and to get on and off at will. Viator booking rate saved us a few dollars off of the posted fare.
