We did the road to Hana a few years ago, with just the info packets from the concierge at our Hotel. We all got a little car sick and didnt feel like we got much out of the trip.
This time, we downloaded this app and man, was it worth every penny and then some! We LOVED the Road to Hana!! The narrator to our tour was amazing. He does such a great job informing you on each stop, why you may or may not like it, and he gives the 5 most absolutely "To Dos" on the Road to Hana. We experienced so much more this time around, and were able to do everything that we wanted to do and in great timing. The narrator even shares really entertaining stories about most of the areas along the road to Hana and what makes them and the villages around unique. He also shares history of Maui and the Hawaiian islands. And an added bonus, he lets you know what food stops are the best!
This is a must for the Road To Hana!! Dont try without it!
