Hi, i have plan to go to gubei water town in morning, 18 of July.

I have plan to visit Chatau Wine (im not sure with that name), Simatai Great Wall and in afternoon, visit Water Town. Did Chetau Wine and Water Town is in same area ? Can you give me information about the schedule bus, the first bus for 980 from Dongzhimen and the last from Simatai, and the bus in Simatai, what time the last bus from there. Because i just want to visit that place in 1 day, and go back to beijing at night. Thank you for your information.
