Horrible experince with Viator. I am a service member and was given orders to report to duty on the date of my tour. I called and tried to rescheudle and they would not. They wanted to charge me 400.00 to rescheudle or just cancel. They were rude and inconsiderate and they ended up canceling the tour since I told them I could legally not attend due to my orders. They have sent me emails stating that I was rude for canceling within 2 hours. I will never book again and will let all my fellow soldiers know not to as well since they do not care about military members or assist them when they have military orders. Terrible christmas experience.
