My wife and I will be taking a long awaited trip to Buenos Aires this winter, and she has hinted that she would like for us to hire a professional while we are there(we are active swingers, so it's really not that big of a surprise).  Is this a relatively safe activity here and does anybody have any recommendations?
Thanks much.

Vinnie,

You will have a great time. BA has some of the most beautiful women in the world. It also has some of the best food. Brush up on your Spanish, many speak no English. Also, be prepared to stay up late. The night life starts late and lasts into the wee hours. Take your vitamins. Give us a report when you return.
