Wife and I, 70+ years old, are frequent international travelers and often hire private tour guides. Some work well, some less so. Always looking to research best options. My advice in visiting Great Ocean Rd from Melbourne: your search is over…call/write James. You can see from other reviews all his attributes. What I can add is that our experiences was that even when he can’t give the tour himself he chooses another good guide… and then he, James , worries throughout the tour that all is good even when he’s supposed to be on vacation. In our case, Max filled in for James and was a courteous, attentive, informative, interesting, pleasant driver and guide for our 2-day tour. Together, James and Max teamed up to take care of a last minute hitch that was weather-related… seamlessly. Also, if you can afford the time, I highly recommend the 2-day option to better enjoy, at a more relaxed pace, the beauty and culture of the local stops.
