Small group travel is the only way to go. Our van and driver (Wayne) were truly first class. We were able to stop in places the large tours could not. This created better photo ops and a more intimate tour. Our snack and lunch were first rate as well. You will not be disappointed.
Quite disappointed with the food. We were picked up at 7am and was looking forward to breakfast of bagels, cream cheese and fruits but got a slice of pound cake each and coffee and juices. As far as the "gourmet lunch", it consisted of 2 kinds of wrap - chicken and fish wrap, some fruits and store-bought brownies. Although, it was nice to have only 8 people in the van so you don't have to wait for a lot of people and your tour moves faster. The driver was very informative and kind. The actual road trip to Hana was beautiful and breathtaking. If you get motion sickness, I suggest Gravol, lots of turns. I wouldn't recommend to parents with young children, a lot of in and out of the van to view different falls, coast line, etc. Overall, I found this to be overpriced.
