I made a reservation a few days before we arrived in Honolulu. Gave my flight # and received a confirmation. Nobody was there to pick us up, so I had to call and tell them I had been waiting for 40 minutes after I got my bags. They said I should have called but never told me I had to do that when I made the reservation.
Anyway, we were finally picked up, and taken to our hotel, near the end of the trip the driver started making U-turns to get to our hotel and we almost got hit twice. Then he tried to go into the underground parking at our hotel and the top of his van hit the roof so he had to reverse out of there.
After getting our bags out of the van he said we owed him $51.00 for the round trip for three people, otherwise it was $10.00 each for the one way, although I had booked my reservation on-line at at total of $42.00 for the three of us return trip. I was tired after 12 hours of travelling and he was a big guy, so I paid him the $51.00 + a few bucks tip. (not thinking clearly!)
That night I started thinking about how wrong this was, why was I being charged $51.00 instead of $42.00, so I e-mailed them about it twice during our stay, and they never replied to me. I worried through my whole vacation that they might not even pick us up to take us to the airport on the day of our departure, but at least they did that. I did not tip when dropped off at the airport. So basically beware of what they charge you, print what you see on the website and bring it up before handing over your cash, maybe even before getting in the vehicle. And wear your seatbelt!!
