Absolutely terrible experience. Avoid at all costs. My friend and I purchased an itinerary, which ended up entirely different from the tour we got. We ended up going to the same location twice in two days, which ruined our last days in Israel. We were the only two on the tour of nine who had this issue. Viator did not bother to notify us of any changes to our itinerary. Had we been notified of the actual itinerary, we never would have purchased it. We went out of our way the day before our tour to visit a location that the tour group then went ahead and visited. We wasted time on our once-in-a-lifetime trip thanks to Viator. When we realized we were seemingly on a different tour from what we purchased, we brought the issue to the attention of our tour guide, who couldn't do anything to help and referred us to Viator. Viator insultingly offered a 10% discount after much back and forth and more wasted time. Ultimately, they refused to make us whole and acknowledge their error. What kind of business doesn't offer a full refund when you get something other than what you pay for? Their customer service was unfriendly, unhelpful, and inept. I will never take a tour with Viator again and caution you against it, too. You not only cannot trust their itineraries, but also you cannot trust their integrity in the aftermath of a mistake that they themselves commit. Our trip was marred by this incompetent company, and that's something we can never get back.
