I plan to travel to Dubai and i know that they use AED (Dirhams) as curency. I'm from France and I would like to know if it is better to go to Dubai with American dollars or euros? Where should I exchange them? in France or in Dubai?
I would recommend withdrawing AED from an ATM in Dubai. There is likely an ATM in the airport so you can do this as soon as you land.
The ATM will charge you a flat fee for withdrawal, while money changers will charge you a percentage of what you convert.
