Yesterday we drove from Waikoloa Resort to the Botanical World Adventures to do the zipline tour. My wife and I are in our 60's, have never zip lined before and, I must admit, she went along under protest :). We had a blast! Kevic and Royce were great with us, very patient, great instruction, found exotic fruits to taste, took great pictures and made the experience more relaxing and fun. The scenery was beautiful. We recommend the early morning zip at 9AM before it gets too hot out! Our only suggestion to improve would be to build some decent bathrooms :).
