The sites we saw were great. I learned a lot about Hawaiian spirituality. The guide knew a good deal about the various sites. However, she seemed a bit disorganized about what all we were going to see. Another thing was that when she wasn't telling us about sites while she was driving, she turned on the radio. LOUD. When she'd start talking again, those of us in the back couldn't hear what she was saying. We asked her several times to turn down the radio, which she did, then cranked it again when she wasn't talking. There is nothing wrong with silence when there's nothing to say. It gives the guests a chance to absorb the scenery and also be able to think up questions. The radio either shouldn't be on at all, or kept at a lower volume. The guide was very difficult to hear even when the radio was turned off as she's somewhat soft-spoken. It would help if she had a microphone like many of the other guides we've encountered. There are a variety of hands-free devices she could have used. It would have made the tour SO much better.
