No public displays of affection: If you are travelling to Dubai with a girlfriend or boyfriend, it is important to know that outside of marriage a number of things are deemed illegal. Sharing a hotel room together outside of marriage could land you in a police cell, whilst holding hands, hugging, or kissing in public places is considered an offence against public decency. It is advisable to simply keep your hands to yourself during your stay.
Do not sunbathe topless: While this may be acceptable on beaches across Europe and in other countries of different cultures, in Dubai it is strictly forbidden. It is acceptable to wear swimsuits, just as long as they aren't too provocative.
Remember that you’re immersed in a completely different culture, and that following these guidelines is not only respecful, but expected too.
Don’t take photos without permission: Dubai has some fantastic architecture and traditional sights to photograph, and it is advisable for any visitor heading out East to have their camera battery fully charged for all the photos they'll undoubtedly take. Some of the more interesting images you can capture on camera are those involving locals engaging in their cultural and religious beliefs. However, it is important to note that local people wearing national dress may well take exception to being photographed without permission, especially women wearing national dress.
It is best just to ask rather than to lose your camera and be hit with a heavy fine to boot.
Stay away from cheap desert tours: Lots of tourists come to Dubai and immediately book themselves on a desert tour. There are endless operators taking visitors out to the surrounding desert; however, the quality of the tours vary greatly from company to company.
