We stayed in Kona once..All kinds of independent coffee shops on the Kona coast. As we all know a major producer of coffee..Can't vouch for income, but they certainly seemed busy...A coffee lovers paradise...Sort of cruise the coffee plantations the way wine lovers cruise the vineyards...Tourists gadding about trying out the new brews. Think I can recall cycle/tourists moving about the island with panniers on...No wonder, one island big enough to cover in maybe two days-if you want to.
