If you have decided to visit places outside the Sharm area, ie. Dahab, Cairo etc, you will a need a visa, which will also be needed if your stay is over 14 days. This can be obtained for $15 on arrival from a Bank/Visa booth inside the airport terminal. There you can also change your money into Egyptian Pounds (LE). There are ATMs, banks and money changers in all the main resort areas. The rate is approx. LE8.5 to £1. Generally the rate is better if you change your money in Egypt.
Pick up a ‘Mix’ or a ‘Sharm Weekly' magazine from ‘Arrivals’. These are English language publications full of ideas of things to do, up-coming events, restaurants etc.
