I used Duke's when we were visiting Oahu for my parent's 50th wedding anniversary. I was VERY impressed with all aspects of my expereince with Duke's. I had researched many places online, received quotes, etc. Duke's was very reasonably priced, and did an excellent job communicating ALL costs up front - the time for their transportation, our travel time, gratuity, taxes, etc. I was VERY impressed! The vehicle was great - very clean, nice and comfortable! The driver was excellent! Our driver even took the time to talk with the people at the luau to make sure we had transportation arranged back to Waikiki after the luau (our last stop with him). He really went above and beyond!!! Everything was handled so professionally, and really went smoothly! I would HIGHLY recommend Duke's, and will use them again when we return to Honolulu!
