If you are staying in Maui a week, I would recommend driving the road and staying in the Hana area one night. There are many scenic stops on the way to Hana and great hiking and the Seven Pools. Get Maui revealed as another poster suggested.
The road was not scary to us in the daytime. It is very beautiful. However, the road is scary after dark. We did the return trip after dark the second time we drove to Hana. Never again. There were locals going fast in pick up trucks after dark and lots of blind curves. I would never try to go and return in one day again. We enjoyed it much more when we stayed at the State Park and had time to explore.
