Just arrived on the west-coast (Jeddah)

Dear all,
After few weeks in Dammam waiting for my Iqama, finally I reached you on the west-coast. I am based in Rabigh (upnorth) and I am thinking to come in Jeddah tonight or tomorrow to 'enjoy' the weekend.

This is my first weekend here so I don't have any idea to what's there to see and do. I'll probably come with some collegues of mine.

Do you have any suggestion?!

Thanks a lot
Andrea
