I will never do business with Viator again, and suggest you do the same. The quality of the tours they promote are terrible but what is worse is their lack of customer service and empathy. Four phone calls arguing with them about a cancellation policy where they clearly stated that the tour needed to be cancelled outside of five days before the tour. It was. Yet, they argued with me that it wasn't even though they sent a confirmation email that was time and date stamped. Then, they tried to say that I didn't cancel on UK time, but I did. Finally, on my fourth call they admitted that they had quoted the cancellation policy in error, but I was still on the hook for $600 dollars. They asked me why I cancelled and I said a family death. They then proceeded to send an email requesting several documents to prove the death. No empathy at all. Absolutely horrible company to do business with. There are so many wonderful options for tours when you travel. Consider Tours by Locals or work with your hotel concierge to put a tour together just for you and your needs.
