traveling from hotel to wall then to airport?

You are advised to rent a private car with a driver for a day. The driver will pick you up at your hotel and then drive you to the Great Wall. After the tour, you will be directly transferred to the airport.
The driver has the responsibility to help you take good care of your luggage when you climb the Great Wall. In this way, it is very convenient and helps to reduce troubles. As for the fee, it is about CNY1,000 at least for one day. You can bargain with him.
