Bahrain
It is easy to overlook this small island-nation, having, as it does, such powerful and flashy neighbours as Qatar and the Emirates, but to ignore Bahrain would be a huge mistake. It is an emerging power in the region, with all the luxury and worldliness of a cosmopolitan destination and all the charm and personality of a small island. Add to this the growing arts scene and burgeoning international cuisine in the country, and you have the newest prime travel destination in the region, and the most socially liberal one, to boot.
