Two of my friends and I went on a Viator Tour of London on April 26, 2024. We were promised we would see the Changing of the Guards at Buckingham Palace and High Tea at Harrods. We did not get to see the Changing of the Guards. We saw the Guards line up outside of their barracks and get ready to do the actual ceremony. We were not even that close to Buckingham Palace. Our High Tea at Harrods consisted of 2 scones and a small pot of tea. Everything I've read about High Tea is that consists of small sandwiches, scones and petit fores. The Viator guide told those of us going to High Tea at Harrods not to eat too large a lunch because we would be getting so much food at Harrod's High Tea. Maybe Viator don't know what Harrolds is providing since the guide left us for the day at Harrods and did not stay to see what was provided. All in all, the two most important part of the Tour of London were great disappointments.
