Our office is OPEN 7 days a week from 8AM to 7PM. Phone number - (808) 561-2440. After hours phone calls are often answered, so please try anytime that is convenient. We also accept text messages. We are finding that email is a more efficient method to communicate due to your and our busy schedules. Our email address is HummerToursHawaii@yahoo.com. We can complete the entire booking process by email, or telephone if you prefer. I highly recommend that when making a reservation you make the reservation directly to KOS Tours, using our email or telephone. Please note that the shopping cart on this website does not work . We specialize in very small group and private tours and a shopping cart booking system for small groups has not proven to be efficient.
