Michael was personable and knowledgeable and I learned a lot on the drive to the wall and at the Great Wall that I didn't know. He suggested we leave early to beat the crowd, and that turned out to be great advice. We got through the line, up the tram, and to the top of the wall with minimal waiting. Not only was there no crowd, it was blissfully cool at that time of day, which all the clambering about much more enjoyable. By the time we came down, the temperature was heating up and the lines were long. It was a very good call. The minivan up and back was also very comfortable and the driver was excellent. All in all a great trip!
