Beautiful country, Muscat is lovely, cracking houses (although you can't buy property) and everyone has amazing cars.
Great beaches for playing football and evening walks, the geology is fantastic.
Certainly a married mans destination rather than a single mans, would be difficult for a single man to find woman as majority wear Burka and I believe are off limits for People of Christian or other religions.
The locals are incredibly friendly and feels like a very relaxed way of living, my impression was its a very family orientated country.
Lovely place to bring up the family and as far I know there aren't too many internal political, religious tensions at the moment.
I think it would be much easier to integrate if of Islamic religion as the day is focused on prayer with prayer breaks every few hours and prayer rooms in every office. I think it would be lovely place to live
