Been there and it was awesome! Glad I went before the civil wars in Syria and Yemen because now I'd feel really bad about supporting a country that refuses to use their vast wealth to help the poor and vulnerable in neighboring countries. Pisses me off so bad.
I have a friend who moved there recently, people get paid double what they get paid for the same job here in the UK and its basically like Vegas with more Muslims and big pointy buildings... and they have a good cheesecake factory.
I've been to Abu Dhabi, which I think is very similar. Damned hot during the day, so we only went out in evenings. Center Hotel was excellent, with a swimming pool and a great bar! Food was 1st class, too.
It's going to be a bit pricey but overall it's amazing. The cops drive around in race cars and anyone of value out there have tigers and other dangerous animals I their cars to show status. If you have the money, GO!!!
