I didn't know she had been with Context.

Think of Viator as being the Craigslist of things to do. It's just a bulletin board. If a person thinks they can do a tour, a cooking class, or whatever, they pay Viator a fee to be listed on their website. That's it. There is almost no vetting. It's just a bulletin board. If someone then uses the Viator website to book that person, Viator also takes a cut of that.

If you go on Craigslist to buy a used car and it turns out to be a lemon you cannot call Craigslist and complain, "I just bought a car using your website, and as soon as I drove it the engine failed." If you can actually communicate with someone they will say, "Why are you calling us? Speak to the person you bought the car from! We just connect sellers with buyers."

They are just a bulletin board, the opposite of something like Context Travel. I am saying this with zero conflict of interest, personally, financially, or in any way whatsoever.
