I do not think we have passed judgment on what Dubai is like, but it needs to be remembered that almost all the gulf states, including, especially, Saudi Arabia have oppressive rules governing women's lives and are even more hostile to anyone who is not heterosexual.
They all have records of the arbitary arrest and torture, of trials without due process of law and a total contempt for anyone who is not a fellow arab. this is why immigrant labour is treated so badly and so many Europeans find themselves charged with crimes that are never properly defined and then left for months and years unable to leave the country or do anything else.
These states know that their wealth, as oil nations, is going to die over the next 30 years. That is why they they are investing massively in the tourism industry. They need your money.
