No one would want to leave canada and come to qatar unless if the money is good. Weather u live in Doha or Al Khor, it wont make a difference cuz there isn't much to do in Qatar as it is. Al Khor on the other hand is a quiter place, appartments might be cheaper since its outside doha, dont know much about social life, but Al Khor being a small city it has a better things around, the beach is close by, there's almost everything in Al khor, LULU is opening up a branch of their super stores there and I believe people are more social there, since everyone knows each other from work. I suppose the company you will work with at Ras Laffan would provide you the accomodation aswell, wont they?

It's always the small things that make big differences.
