Doha is same as Q8 but you can get a drink. Apart from that, all the other comments apply. The differences are not of an order of magnitude and the caveat that Doha is more xpensive holds true. If you can hack GCC countries this has the most potential imho. Give it 5 years and it will have a GDP in the stratosphere which will be 'interesting". It is a boom town and there is a certain palpable sense of goldrush about it albeit regulated ( so far).
