If you are not interested in a taxi, disregard this. We arrived at HNL last Christmas and grabbed a cab at curbside to the HHV. Fare and tip were about $30. On the way back, I used a coupon from one of the weekly event books and the same ride in reverse cost $15 for the fare and tip. I asked the dispatcher why it was 1/2 price and she said that if you call, it's cheaper since they don't use the meter.
