When a space on a tour is sold, it is removed from our tour inventory and no further attempts are made to sell that space. Some destinations require a certain group si e to guarantee special services and rates. For this reason, all trip deposits are completely non-refundable. Once final payment is made, it, too becomes 100% non-refundable, whether or not the trip eventually sells out. If you cancel at any point, your money is forfeit, period. NO exceptions. we strongly advise our travelers to obtain trip interruption/cancellation insurance in the event of a forced or unforeseen trip cancellation.
