I looked at several Limousine companies on Oahu to find a good one for my parents 50th wedding anniversary, and Duke's was GREAT! They had good communication, were timely, and took care of us the entire time! We had a great limo and a great time, and our driver was wonderful!!! After dropping us off at our luau (our last stop), our driver spoke with the people at the luau to make sure that we had transportation back to Waikiki from our luau. He went above and beyond, and we appreciated it!!!! Duke's was very reasonably priced and communicated all parts of the costs (travel time for us and the limo, taxes, gratuity, etc.) from the beginning! I would HIGHLY recommend them, and will certainly use them again when we return!
