August 26th 2016 I arrive at Beijing Capital Airport and need to go to Holiday Inn Express Dongidime

Do you refer to the Dongzhimen branch? If so, you can take the shuttle bus or the airport express to Dongzhimen at a cost of CNY25. Get out from the Exit E, walk east for 800 yards, and then turn south onto Chunxiu Road for another r450 yards, you will reach the hotel.

Or you can take a taxi, which may cost you CNY70 around.
