Booked the same excursion with Viator 3 times because it kept showing available on the web site. After the third cancellation I called to get some answers and was told that the dates I wanted (which showed available on the website) were not available. Asked for other options and were quoted similar excursions that were much more expensive than the one I booked 3 times. Asked them to match the price but was told they have no authority to offer discounts. Asked again why the tours still showed available on their website if there were not available and was told “I don’t know”. I will never use this company again and would recommend that others stay away.
