During our Iceland cruise I booked a few excursions via Vitor.com The excursions were great, except for the Lake Myvatn, Hot-Springs & Godafoss Waterfall Tour from Akureyri excursion. Because our ship could not dock in Akureyri due bad weather we unfortunately could not participate in this excursion. I contacted Viator directly by email to explain the unfortunate situation that occurred through no fault of our own and to find a solution. There was no substantive response by email and answers of Viator.com customer service where evasive. The only solution offered by Viator was to do the same excursion again at another time. Because Iceland is a once in a lifetime trip for us this is a worthless offer from Viator. We simply are unable to claim this offer in the future so our money is gone! We travel often, and always book through Viator.com but this was the last time. viator.com takes no responsibility, instead they shift the responsibility to the supplier. I booked with Viator.com I paid Viator.com I have an agreement with Viator.com No chance of getting out of responsibility this way. The only correct solution would be to be allowed to use my credit on another Viator.com trip or to credit the amount paid. Once again, worthless service, one star for Viator.com Stay away from this company if you expect service and book your tours elsewhere.
