This is currently Dubai's off season.

I hope you have researched well even though this business goes on there it is a place I sure would not want to get caught.  I hope you are staying at a very busy hotel.
Good luck safe travels and remember to book a Friday brunch.

I've heard that the guys haggle over price and quite a few don't pay at all since the providers have little recourse.  Don't argue with the Johns and keep a low profile.  See these newspaper articles:

It is still nice to travel to Dubai , but Police is every where.
Stay safe!!!
