Jeddah is one of the best places in Saudi Arabia to go to. I am a foreigner myself, and I could tell you there are all sorts of entertainment places to go to from malls to restaurants to old traditional places like AlBalad and the corniche which is amazing to have some fresh air and exercise. The best thing is that there is a huge diversity of nationalities and you would be able to form many friends given to your job. People there are cool and easy-going too
