The information and coupon booklets such as "This Week on Oahu" available at hotel front desks will give you an idea of the variety of limo services available in Honolulu. I tried one of them on my last trip to Oahu 2 years ago-Executive Towncar Service-andwas very pleased at the level of service I received. Their 24 hour phone number is (808) 429-4710 and they're located in Honolulu, but they can drive you all over Oahu. Craig Maeshiro is the owner and he was also our driver. He arrived to pick us up in a Lincoln Towncar that he kept immaculate inside and out. In the back seat waiting for us were cold bottles of water, at each stop on the custom tour we arranged, he stopped and took digital photos of us, which he then printed out at our destination hotel and placed in cute little Hawaiin frames for us. He even bought each of us a frozen treat- chocolate covered bananas- when we stopped at the Dole Pineapple Plantation. These nice little surprise extras were included in the tour price. My friend and I were so impressed, she said now she knows what royalty and movies stars feel like when they are treated with the utmost of respect on their journeys. So I would say that whether this trip to Oahu is your once in a lifetime dream trip or you are a seasoned island-hopper, you should try being spoiled on a trip just once, to see what you've been missing.
