I had been waiting for years to visit the Smithsonian African American Museum in Washington, DC. I’ve had experience with Viator in the past so, didn’t hesitate to book through them again. Previously, I had received reminder Emil’s, text messages and finally, phone calls when transportation was on the way. This time, didn’t happen. So, I took an Uber from my hotel. When I arrived at the museum, I waited in line, like everyone else. Still no guide and no contact information for the guide. Even worse, when I got to the entrance to go in. I showed my Viator pass to the person checking tickets and was told that our tickets were invalid. Then security was called. The security person checked our tickets and informed us that these were UNAUTHORIZED and unacceptable. I have never been more embarrassed. I explained to security and the person who spoke to us originally, that I had traveled hundreds of miles to be here and thought that I was purchasing valid tickets. Luckily, the two of them sympathized with us and granted us entrance. Afterwards, I contacted Viator, told them of my experience and requested a refund. I was denied. Never again.
