"It's a unforgettable tour. Thanks for Adam's guide, our family enjoyed everything in Oahu, including many recommended private stops. I really recommend you to choose PTH because of not only the 100% flexible schedule and vivid explanation(with quite slow speed for us), but also the perfect "pre-sale" service. You can ask Adam any question by email, and he always replied so quickly. My family and I did enjoyed our vacation in Hawaii this summer."
