TourRadar had a great selection of tours at a variety of prices. I chose one to China and one to Japan. The website was generally easy to use and very informative. One problem I did have was that the China tour required me to add a single supplement after I had been told by a TourRadar agent that none would be needed and that I could sign up to share a room. The Japan tour was unfortunately sold out, so I had to select another one. To get the overall trip sorted out, I did call customer service multiple times and talked to a number of people. Everyone was great and very helpful. I would use TourRadar again.
