I booked a tour on May 6th, and because of heavy traffic I was a couple minutes late. The tour guide saw me and left in my face.I notify Viator, and to my surprise, Viator said "The booking terms explicitly state that in the event of a no-show or last-minute cancellation, the full booking amount will be forfeited"., which I have neither no-show nor wanted to cancel.This is not a trustworthy website anymore, you have be warned.
