I survived the Road to Hana! ;) For most people, the Road to Hana is a one-timer because it's an all-day trip. It takes half the day to reach the top and half the day to drive back down. The road is narrow and often turns into a one-vehicle lane. The first hour or two of the trip is fascinating; after that, it's pretty redundant until you reach the Pools of 'Ohe'o. The drive is long and there are few stops, so bring snacks and drinks if you plan to experience it.
