The camp operator was fined Dh50,000, while each guest had to pay Dh15,000.
Video footage released by Dubai Media office showed a large stage erected in the desert as strobe lighting darted into the skies.
The specific location of the event was not disclosed, nor when it took place.

The licence of the yacht operator was suspended for a month.
Last week, tourism chiefs said tours or parties on yachts would be restricted to 10 people in response to a recent rise in coronavirus cases.
Previously, vessels were allowed to sail at 50 per cent capacity.
