Do not trust Viator! They will not do anything at all to help you if you get ripped off by one of their tout listings, they will not even respond to you. We booked several excursions for our family vacation in France through Viator, and when we had customer service issues and were not provided the services as described, Viator did absolutely nothing about it. Did not ever reply to us! We spent over $1,500 for a Private, Guided tour of three castles in the Loire Valley. The listing says specifically "Professional Guide" The reviews all talk about how knowledgeable the guide was, and how much information he had for them. For our trip there was no guide at all. I asked the drive if he would tell us about the valley and the castles before we arrived, and he said "I am not a guide, I am only a driver" He said he did not know where the guide was who usually rides with him!? So we drove for 2 1/2 hours to the castles in Silence! We told Viator this is false advertising. The listing says specifically Professional Guide. We were not given the one main element of the trip we paid for. Viator and the tour company did not even respond to us. We emailed, called and reviewed the company, no response at all. Viator completely let us down. We also booked a Private Van to shuttle us from the airport to our hotel. They ended up leaving us standing in the airport for 90 minutes waiting. Every single other person on the plane had been picked up by the dozens of shuttle drivers waiting at the airport. We were the last group of people by far. So, it could not have been the traffic. We called the company multiple times while we were waiting at the airport. They had forgotten about us. They sent a taxi instead, and he said he could not fit us. He said to us "I will be right back" Then literally walked out of the airport and just left. So, we had to call again and ask where is our private van we paid for?! So, we had to sit and wait and after 6 or 7 phone calls and 90 minutes later a van finally came. Isn't that a great way to start your vacation, after a 10 hour flight? You try to book reliable transportation for your family and end up with a headache trying to get to your hotel. We ask for a partial refund. No response from the company and Nothing at all from Viator. Viator will not help you if you have any issues with their listings. Even blatantly false advertising, they do not care and will not advocate on your behalf. The tour companies listing their services on Viator are their customers whom they make money from, not you. Do not trust Viator!
