Dubai’s Department of Tourism & Commerce Marketing (DTCM) is the official tourism board and government body responsible for regulating, planning and licensing the city’s tourism and hospitality industry.
The DTCM is headquartered in Dubai but also maintains offices in many of the world’s biggest cities (London, New York, Tokyo, Beijing, Moscow, Frankfurt, etc.).
Visitor Information Bureaus
Visitors to Dubai wishing to obtain maps, brochures, public transport schedules, and general tourist advice can visit one of the DTCM’s Visitor Information Bureaus. They can be found at the airport and several shopping malls (Deira City Centre, BurJuman, Ibn Battuta Mall, and Wafi City Mall).
Official Dubai Tourism Websites
The DTCM maintains 2 websites:
Government of Dubai – Department of Tourism and Commerce Marketing
The official site of the DTCM offers a wealth of information in addition to general tourist advice. It features an excellent interactive map, press releases, useful tourism statistics (hotels, visitors etc.), legislation and laws, videos, a weekly newsletter, an online complaints service, electronic brochures, and more.

Business Visitors

SO just because a "kissing" in public arrest has been made? stay away?
No offence or not tryign to argue, but thats abit silly advice John 
Its called respecting religion, Dubai is an AMAZING place
After the recent arrest of the two British nationals for "kissing" in public. I urge everyone to stay out of Dubai.
Summer is a good time to go to Dubai. The weather is very hot but flights and hotels are a lot cheaper.
