We booked a half-day hike. Dealing with Scott was easy -- I emailed him with dates and our skill levels and he responded right away with 3 different options that would work, and we picked one. He took us along a route where we saw NO other tourists -- only 1 local and a sea lion! It was great to do a hike where there weren't a thousand other tourists. Next time we are in Hawaii, we will be doing a full day hike with Scott.
