My husband and I will be visiting Beijing October 13-16 and we plan to visit the Great Wall Mutianyu. I have read a lot of forum posts on transportation and have a few questions. I am looking for responses from travelers who have visited Beijing during or since the Olympic Games. Does a return trip taxi to Mutianyu (waiting for approx 3-4 hours while touring wall) cost 350-400 RMB? Have prices gone up since the Olympics? Would this be the expected price for a taxi flagged on the street or one arranged by the hotel? Also, I have read a lot of good reviews about hiring a driver named John. However, when I emailed for a price quote I was quoted 1000 RMB which seemed a very high price. Has anyone used a private driver in Beijing to go to Mutianyu since the Olympics? Have the prices for private drivers gone up? Thanks for your help.
