During I worked in Kuwait 2000 for 6,5 months, Kuwait people camped often in the desert at weekend.
They use complete equippment like power generator for light and TV.
Also water car for shower.
I remember there was also offizial camping places, but just only a place nothing else.
It is about 7 - 8 degree hotter than Emirates.
It means expect e.g. over 40 degrees even end of October and also over 40 degree can reached in April.
There are some areas marked with sign for risk of land mines.
