We take Visa, Mastercard, and Discover Cards. Your card will be charged at the time of the reservation for the full amount. If you cancel outside of the cancellation policy, your card will be refunded in full minus a $20 processing fee. If you cancel within the cancellation policies, your card will be charged 50% of your total plus a $20 processing fee with the remaining balance refunded back to the card used to reserve the tours. No refunds will be given for “day of” cancellations or no-shows. Cash payment options are available. If you wish to pay with cash, it must be prepaid in order to make the reservation. Please note with cash payments we require a credit card to be on file to hold the slots. We require this because out tours are in sequence and for the guests convenience, we allow upgrades while out on the tours. The Credit Card on file covers upgrades so our guests do not have to come off the tours to pay for each upgrade. Guests may come back and pay cash for upgrades, but if they do not come back to check out, the card will cover any and all upgrades completed. We do not take personal checks.
