At least Icristler seems to have done a bit more research than some people who just put their rose tinted glasses on for the interview and believe whatever they are told- whilst ignoring everything they read here.
I would caution that what you see in one week during the interview isn't the "real" Dubai- recruitment are very careful to give you the sanitised version. I would suggest that anybody making such a life changing decision takes at least a week's holiday as well as the time spent during the interview to get a really good feel for the place. Have a look at the prices in the supermarkets and other shops and compare it to an F/Os salary. Then remember that your pay rises may be minimal for the next 7 or 8 or whatever years until you upgrade but infaltion hasn't been minimal here for the last decade or so.
It isn't for everybody but some people (a rapidly shrinking number) really do love it here.
Oh, and if you think the heat here is going to be just like Arizona, you may be in for a bit of a surprise.
Good luck, let us know how you get on once you arrive.
