I travel to the GCC 4-5 times a year, usually making a pit stop in Dubai.
The party changes every 3-4 months to avoid detection.

In the past the party used to be at the old Dhow Palace ( Club Submarine), this place has closed.

The last time I was in Dubai the party was at Hewes Hotel, I am sure this venue has changed.
Also there is a separate scene in Abu Dhabi
