Thank God I found this app before exploring the Road to Hana. Without it, we would have, no doubt, missed almost all of the attractions, vistas, and nooks n crannies that made our day trip one well remember forever.
The tour guide was knowledgeable and it was clear he is a local or knows Maui inside and out. We jokingly named him "Padre Bonneigh" (completely random) and felt he was our personal guide at the end. The ride back was great as well, as he saved some local history lessons to keep us occupied.
Especially helpful was the fact he let us know which sites are must see and which can be skipped depending on time.
We will definitely be using GyPSy in the future for any and all sightseeing for which they have tours. I wouldnt have wanted any other in-car tour guide experience, format, guide, or otherwise.
