Can an escort visit my hotel in midnight?

While, if your hotel is a four-star or five-star hotel, it will be ok to visit your hotel in midnight. But if it is a three-star or economy hotel, I will suggest you to call an escort to your hotel at an earlier time on the next day i.e in the daytime or early evening before 9pm. But please note that for those hotels (even Five-star hotels) in Wangfujing area in Beijing, visit by an escort is usually not allowed after 9:30 pm.  So be careful to select your hotel before you visit China.
