Phone calls within the UAE are free, unless made from a public telephone. Dubai is a cosmopolitan city and that means you should have no trouble hooking up to the net. If your hotel doesn't have access, check out one of the numerous internet caf s available in the city. Like most other businesses in Dubai, it is possible to negotiate for your hotel fees. Just make sure you do so before booking your room and giving your credit card information.
Roads are in good condition and rental car rates are reasonable.
Avis, Budget, Hertz, and Thrifty all have desks at Dubai International Airport. When driving a rental car, make sure that you are properly insured. Of particular importance is diyah payments insurance. UAE law states that anyone responsible for a fatal accident must maintain the family of the deceased. Diyah insurance will take care of these payments.
