I am heading to Egypt soon and was wondering what the best currency was to take. US dollars or Egyptian piasters (is that right?)?.
Take some USD (or Euro) as back up only.
Having been in Egypt recently you will get much better prices using Egyptian Pounds (LE). Be wary though in the markets - make sure that when you are haggling, make sure they know you mean Egyptian Pounds not Sterling - some traders will try to tell you that the price you just agreed to was British Pounds!
