Hi Man,
Frankly speaking, it is not a good time to enjoy a service in a sauna in Shanghai now. Maybe you have not heard about something of raid in saunas, night clubs in most of metropolitan cities such as Shanghai, Beijing, Guangzhou etc. If I were u, I will not take any risk considering your good job in LA. I will rather consider a safe say to call an escort girl to my hotel. Anyway your hotel is a five star hotel, it is safe.
If you like, u can visit my blog: escortshanghaiveteran.blog.com and you will get all of the info u wanna know. I think I can help u. Do not think I am just pushing sales of my blog. I do suggest u not to take any risk at the particular season.
