I am looking for transportation options (other than a car) to get from Waikiki to Ko Olina and back, and on another day from Waikiki to Turtle Bay and back. We will be four guys golfing, and most likely will be intoxicated, so we are looking for a cost effective way to these two locations on separate days. Any idea what a taxi would cost roundtrip to Turtle Bay? and to Ko Olina? Are there shuttle buses available for these routes? Cost?
