I moved to Dubai beginning of May, so far so good
Nightlife here is ridiculous, always something going on.. Another big thing here's the brunches, basically pay X amount of money and its all you can eat and drink. Theres loads of expats here too, majority of the people you will meet wont actually be from the UAE. Its very westernised here so they turn a blind eye to alot of things (drinking, girls etc) just as long as your not openly causing a scene, you will be fine.
Must say the country is the most superficial place I have ever been to though, people assume that because its tax free everything is dirt cheap - depends how your lifestyle is. If you're careful with your finances you will be fine, but if your going out every weekend etc.. Your money will go like water.
