there is lot of hotel close to the ariport,it's easy to find.
if you want to find some escort ,I suggest you to go to a KTV called "hu xiao",very close to the airport, located at "Tian Zhu Cun" .If you take a taxi , 20 yuan will be ok.the price is 100 RMB,you will be allowed to touch and kiss but no SEX ,if you wanna have sex with the ladys, just tell the "mami" I remember her name is "Yan Zi" the cost will be 800 for one night.
have a good time in Beijing.
